The half-life of radium is `1620 years` and its atomic weight is `226`. The number of atoms that will decay from its `1 g` sample per second will be .

The half-life of radium is 1620 yr and its atomic weight is 226 kg per kilo mol. The number of atoms that will decay from its 1g sample per second will be (take, Avogadro's number, N_(A)=6.023xx10^(23) atom/kilo mol)

The half-life of radium is 1620 yr and its atomic weight is 226 kg per kilo mol. The number of atoms that will decay from its 1g sample per second will be (take, Avogadro's number, N_(A)=6.023xx10^(23) atom/kilo mol)

If the half life of radium is 1620 years then its decay constant is

If the half life of radium is 1620 years then its decay constant is

Half life of radium is 1600 years. Its average life:

The half-life of radium is 1600 years . Calculate the number atoms that will decay from 1g sample of radium per second (given, atomic weight of radium = 226)

half life of radium is 1580 years. Its average life will be

The half life of radium is 1600 years. The number of undecayed atoms of radium after 4800 years will be :
