(1998, 2M)

(a) alpha emission

(b) beta emission

(d) electron capture

Show Answer

Answer:

Correct Answer: 11. isobars

Solution:

In the following nuclear reactions, there occur decrease in atomic number $(Z)$

$\begin{aligned} _{Z} X^{A} & ⟶_{2} H e^{4} +_{Z - 2} Y^{A - 4}, α - emission_{Z} X^{A} & ⟶_{+ 1} e^{0} +_{Z - 1} Y^{A}, positron emission_{Z} X^{A} +_{- 1} e^{0} & ⟶_{Z - 1} Y^{A}, electron capture \end{aligned}$

In beta emission, increase in atomic number is observed.

$_{Z} X^{A} ⟶_{- 1} e^{0} +_{Z + 1} Y^{A}, β -emission$
