Element 43 shouldn't be radioactive
Radioactive elements are usually heavy, with high atomic weights. So why is the 43rd element in the periodic table radioactive? Find out here as we dive into the nuclear physics behind the periodic table.

    I'm not sure I understood the answear. Aren't the elements before it just fine with having neighbor elements on both sides more stable?

    • @gabrielhong2800
      @gabrielhong2800 2 หลายเดือนก่อน

      If I understood correctly, what they meant is that any isotope of Technetium that should be stable has another more stable neighbour with the same atomic mass which caused the technetium to decay, the reason why the other elements are fine having neighbour elements on both sides more stable is because they have other isotopes with no stable neighbour elements which allows them to have a non-radioactive isotope

    perhaps the valley of stability only extends further under extreme conditions near or just beyond the event horizon? If time slows down for something near the event horizon perhaps that would allow novel conditions for the development of extremely large atoms?

  • @drakegrimm1287
    @drakegrimm1287 3 หลายเดือนก่อน

    Ok, could anyone please explain this to me? They took the number of protons (Z), the number of neutrons (N) and the atomic weight (A), and checked whether each of those is odd or even. Then they said that "each stable isotope falls into one of 4 categories", as in "each stable isotope is inside one of those 4, and unstable isotopes are outside these categories". But the other 4 combinations of "odds" and "evens" are impossible from the fact that A = Z + N Like you have radioactive Co-60 with even A, odd Z and odd N. And it is inside one of these 4 categories for which they claim to be for stable isotopes

    2:54 --- That's not a strategic omision, that's a lie by omission. The facts don't agree with your simple ideal, so you just decided to pretend you're right.

    • @HeterosexuaI
      @HeterosexuaI 3 หลายเดือนก่อน

      youre not that bright are you? the "strategic omission" is them cutting out the portion of the table that contains isotopes that they are not talking about. he was specifically referring to isotopes 97 and 99, so he removed the portion of the table that didnt contain those isotopes. it has nothing to do with facts or ideals, they were literally just not talking about the isotopes that they omitted. if im talking about divorce rates in the US and i pull up a table about divorce rates in north american countries, it wouldnt be lying by omission for me to remove the data regarding countries that i wasnt focusing on. talk less and pay more attention, you'll have less of a chance of looking stupid if you do.
