Sir, but we can determine that one element nucleus is stable or not by just calculating the ratio of no.of neutron and no.of proton .If the ratio is less than 1 and more than one than 1.5 then the elements are said to be radioactive.(1 1.5)
Thanku so much sir 🙏🙏 Sir for me this is very tough chapter in theory portion but when I see ur all videos which was based on radioactivity this helps me a lot Again thanku very much sir You are a great teacher👍❤
You are doing a great job. Not just for the students but also for the teachers out there.. I am a teacher and sometimes when i am in any doubt i watch your stuff and its pretty amazing.. Thanks a lot.
Sir if unstable radio active nucleus emits alpha beta and gamma than what type of radiation is emitted by elements which are not radioactive but still have an unstable nucleus
As much as I know...if an element has an unstable nucleus, it will release radiations...so basically all elements having atomic number (Z)> Lead(82) are natural radioactive substances..
Sir video was very awesome but sir according to my knowledge the elements which have the atomic number greater than 83 are radioactive you said the elements greater than 80 atomic number are unstable... Actually lead is having the atomic number 82 but it is not a radioactive element... So sir if I'm wrong tell me .. Thanks btw the video was very good 🙂
It is wrong to say that elements with Z proton is radioactive. Eg:- Na having Z = 11 and A= 23 ; therefore proton = 11 and neutron= 12 ; still Na is not radioactive although neutron > proton.

Is fluorine (9F19) Radiioactive ? {As it has 9 protons and 10 neutrons.And falling under the category atomic no < 20}
Yeah 😉😉😉

Very good and interesting explanation. But what about Na stability? Its neutron proton is not equal.

Sir video was very awesome but sir according to my knowledge the elements which have the atomic number greater than 83 are radioactive you said the elements greater than 80 atomic number are unstable... Actually lead is having the atomic number 82 but it is not a radioactive element... So sir if I'm wrong tell me .. Thanks btw the video was very good 🙂

Sir class 9th and 10th ko bhi padhei na please.sir your teaching way is very good.
It is wrong to say that elements with Z proton is radioactive. Eg:- Na having Z = 11 and A= 23 ; therefore proton = 11 and neutron= 12 ; still Na is not radioactive although neutron > proton.
