The nucleus has

If a radioactive nucleus has a half life of one year, will be completely decayed after two year? Explain.

The nucleus which has radius one-third of the radius of Os^(189) is

The mass number of atom whose nucleus has a radium of 5.6 Fermi (R_0=1.40xx10^(-13)cm) is

The mass number of atom whose nucleus has a radium of 5.6 Fermi (R_0=1.40xx10^(-13)cm) is

(a) Define the terms (i) half-life (T_(1//2) ) and (ii) average life (tau) . Find out their relationships with the decay constant ( lambda) . (b) A radioactive nucleus has a decay constant, lambda = 0.3465 (day) ""^(-1) . How long would it take the nucleus to decay to 75% of its initial amount?

Calculate in the atomic mass units the mass of (a) a Li^(8) atom whose nucleus has the binding energy 41.3MeV , (b) a C^(10) nucleus whose binding energy per uncleon is equal to 6.04 MeV .
