    I guess a lot of toxic substances including arsenic are only really toxic when swallowed or inhaled :) Thallium is worse - even simple skin contact is considered dangerous. Good thing that they chose a glass ampoule to contain the thallium.

    Thanks for the guess and kind words :)
    Scandium is tested in the first part of this series. I do need to revisit the rare earth metals though with a more sensitive setup. Also have all of the rare earth oxides to test so stay tuned for more videos :)

  • @brainiac75

    Platinum is a little paramagnetic (+193) so I should easily be able to show that is attracted to a magnet on a water bath. It's just so expensive :)

  • @brainiac75
    @brainiac75  11 ปีที่แล้ว +1

    A lot of metals are, and most semimetals and non-metals are diamagnetic, so you were close to being right. But quite a lot of metals are actually diamagnetic and repels a magnet. I guess it is counterintuitive that some metals repels a magnet. We grow up having fun with metals being attracted to magnets :)
    Thanks for watching!

    It will be a while for part 4 - the last elements are quite expensive. That gold sample set me back on cash :/
    But I have lots of other videos coming, so stay tuned.

    In part 2 I did put the price and availability on every element - but looking back I don't like it. It almost turns the video into a commercial...
    During the credit crunch gold turned extremely expensive - more than platinum. Gold has dropped in price since but still is one the most expensive metals. Silver is quite cheap compared to many other metals :)
    Rhodium samples tend to be extremely expensive because so few people sell it outside the industry :(

    So it's been a week since my upload and I'm surprised by the many guesses on the alloy. Thanks for participating!
    I did make it a challenge and gave very little information in the video (or my brilliant subscribers would guess it within the first hours). Many of the guesses have been very interesting - I have learned about alloys I didn't know off - cool!
    Here's a tiny bit of help to make it less impossible:
    - It's an alloy of two elements.
    - It's not that expensive (~€5/$6 for the shown piece)

  • @brainiac75
    @brainiac75  11 ปีที่แล้ว

    Yes, because I always test the styrofoam alone with the magnet before putting the element on to make sure no impurities, static electricity or just basic draft etc. isn't affecting the result. I also use these tests personally to give a little extra guarantee that I have the element that the seller claim to have sold me :)
    And wouldn't a static charge in the styrofoam be discharged on a water bath? I have yet to see an effect with just styrofom and a magnet on a water bath.

    Radioactivity does not really change the conductivity of a material. Radioactivity is related to the nuclear core whereas electricity is about the electrons around the nuclear core.
    Beta radiation is electrons but even very powerful beta sources would not really emit enough electrons to change conductivity in a metal.
    Alpha sources are however used in smoke detectors to ionize the air inside a metal dome enough to make the air a little conductive (which smoke blocks and triggers the alarm).

    Neodymium magnets that are thin compared to their diameter are extremely fragile. Never let them smash together or fly/fall towards iron. You can wrap them in something like cloth or many layers of tape but you loose magnetic power when you put something between the magnet and what it works on.

    Testing gas with a magnet is not easy because of their low density, that makes it hard to have a significant mass close to the magnet. It is possible with gasses cooled to they are a liquid (search for a video of 'paramagnetism of liquid oxygen') - but I don't have access to liquid gasses.

    The video has only been up for two days so it's too early to give clues. But let me repeat what you can tell from the video:
    1) It's an alloy - so there's more than one element in it.
    2) It has a color - a little more faint than the other three shown but still a yellowreddish color.
    It hasn't been guessed yet :) I'm positivily surprised by the many guesses already - keep 'em coming!

    stupid question: Why can't you find heavy elements like lawrencium,... anymore?

    • @brainiac75
      @brainiac75  10 ปีที่แล้ว +9

      The very heavy elements are extremely unstable and quickly turns into other 'lighter' elements through radioactive decay or spontaneous fission. The half life of the most stable isotope of lawrencium for example is 11 hours. So even if they were formed in freak accidents of galactic proportions they would disappear quickly.
      As far as we know the very heavy elements like lawrencium have only been made by man and never in nature.

      Chan Hien Exactly, the elements above atomic number 100 (fermium) have only been made in invisible amounts in laboratories by smashing smaller atoms together in large man-made machines. A few atoms can be detected in day-long experiments but we have never seen them with our naked eyes.
      Uranium with atomic number 92 is the highest we can collect in visible amounts in nature. Anything above is extremely rare or doesn't exist at all in nature. More info: en.wikipedia.org/wiki/Transuranium_element

    FYI Arsenic in metal form isn't allll that toxic. It gets biotransformed to toxic compounds in your body though - substitutes phosphorus. Single touch should not be dangerous, but you're right, safety first!
    The infamous toxicity of arsenic comes in its ionic form (+III, +V oxidation states), +III being more toxic and +V more carcinogenic.

    Thanks for making that clear. Is there an element or alloy that blocks magnetism without otherwise affecting it ? I am a HAM Radio operator. I have built 'loop antennas' in the past for listening to Medium Wave Broadcasts( AM radio in the US. .5 to 1.7 MHZ.) Loop antennas are also callcd "magnetic loops". They receive only the magnetic part of the electromagnetic wave.They are immune to interference from huosehole interference such as electric motors and florescent light lights.

    the white foam can be energized becouse of the static energy , so when you get the magnet near to the gold, piece, is not pushing the gold, is pushin the foam that carry the gold

    Fe particles in the P are reacting to the magnet. What if friction forces fire P?

    Den viste kobberbarre kan købes på den engelske eBay (ebay'co'uk) - søg efter 'copper bullion'. En lignende koster £25 + £6 hos sælgeren lathe*dog, som jeg brugte. Vil dog anbefale at søge på den tyske eBay først (søg efter 'kupfer bullion'). Der er ofte bedre tilbud - 1 kg til omkring €16 + porto €10.

    Will you finish off the rest of the platinum group metals like Ru, Rh, Ir and Pd in the future? And the rest of the other elements like the Alkali Metals and Ta?

    • @brainiac75
      @brainiac75  9 ปีที่แล้ว +1

      flimsybop Thanks! Yes, over time I will get small samples of all elements I can get my hands on :)
      Part 4 is coming 'soon' - probably in August - and will include a few of the metals you mention.

    True. Rhodium was recently over $300/g. It's now around $30/g. Platinum and palladium are not at a historically low price right now, but rhodium is a bargain.

    Hmm, my first guess was bronze, but someone mentioned Cu/Sn already.
    My second guess was Cu/Al (aluminum bronze) since it is cheap and has some golden color.
    Now since you said non-sparking, and so it probably must be Cu/Be (beryllium copper) which is used to make non-sparking tools. It would also explain the security measure.

    Do you think you'll be able to get a reaction from the phosphorus, arsenic and thallium now with your double magnet?

  • @Xaplelul

    You should do a video about the rest of the elements either telling why samples are unavailable, like price or hazard. Maybe give us a little info about each element and let us know if you ever plan on getting it for your collection.

    • @brainiac75
      @brainiac75  11 ปีที่แล้ว

      During the making of this series so far I have learned that more is available than I ever thought. So I may make an error if I named the elements I can't get a sample off to test. Eg. thorium is very difficult to get but it's not impossible... Money is generally the limitation in this project ;)
      Any element in particular you are interested in hearing about?

  • @brainiac75

    Can have your sample metal when you're finished testing? The yellowish element will do nicely.

    Is there another element that will take permanent magnetism similar to iron that these weakly magnetic metals would be more drawn to?

  • @brainiac75
    @brainiac75  11 ปีที่แล้ว

    Hos en lokal guldsmed for at være sikker på, at det nu var guld. En ret dyr løsning, da der er flere forhandlerled, som skal tjene på det. Guld kan også købes på fx eBay - noget billigere, men jeg turde ikke stole på dem ;)

    Styrofoam holds a static charge very well. Are you sure the repulsion and attraction is not due a static electric charge ?

  • @Stebanoid
    @Stebanoid 9 ปีที่แล้ว

    Cool videos!
    But I just wanted to warn you that the way to test magnetic properties with a sample floating on the top of a polystyrene foam is not accurate enough. Especially if you are using small samples. Water is diamagnetic, so when you are approaching magnet to a raft with a sample, small concave in the water surface is created by repelling force and the raft is sliding down in it. So, it will look like the sample is attracted by magnet.
    I've seen an experiment demonstrating this effect with a strong magnet and a small ball of expanded polystyrene.

    Part 4 for this series? That is gonna be a while - I simply don't have the money for some of the last expensive elements right now. But I have lots of other videos planned. Right now I'm working on one with the mystery alloy in the above video. Hope to release it this week :)
    Thanks for watching!

    Could the potential build up of static on the spherical magnet, cause an interaction with the styrene platform?
    In the case of the supposed gold watch strap, is there not a steel anchoring pin between each link?
