Question

which of the following statement about ²⁴⁸Bk is incorrect?

A) If ²⁴⁸Bk were to undergo beta decay, the products would be ²⁴⁸Cf and a beta particle.

B) If ²⁴⁸Bk were to undergo alpha decay, the products would be ²⁴⁴Am and an alpha particle.

C) If ²⁴⁸Bk were undergo gamma decay, the products would be ²⁴⁸Bk and a gamma ray.

D) If ²⁴⁸Bk were to undergo spontaneous fission, the products would be ²⁴⁷ Bk and a neurton

E) if ²⁴⁸Bk were to undergo electron capture, the only product would be 248Cm.

Answer 1

beta decay leads to mass number remaining same but atomic number increases by one if it -ve beta decay and decrease if is +ve beta decay. Hence A is correct

alpha is Helium nuclues. Its mass number is 4 and hence during alpha emission, there is loss of 4 in mass number. Hence   B is correct.

During gamma decay, there is neither change in mass number nor atomic number. Hence C is also correct.

D is Incorrect because fission leads to break down of heavier atom into smaller atoms.

E is also corret during electron capture.
