Answer 1

Note: The correct question is-

Write down the sequence of radiations emitted in the following radioactive processes.

$_{Z+2}^{}\textrm{X}^{A}\to _{Z}^{}\textrm{Y}^{A-4}\to _{Z+1}^{}\textrm{Y}^{A-4}\to _{Z-1}^{}\textrm{K}^{A-8}$

a) $\gamma -\beta- \alpha$

b) $\gamma - \alpha -\beta$

c) $\beta-\gamma - \alpha$

d) $\alpha-\beta -\alpha$

1. The process by which an unstable atomic nucleus loses energy through radiation is known as radioactive decay.
2. A radioactive material is one that contains unstable nuclei.
3. Alpha decay, beta decay, and gamma decay are three of the most common types of decay, all of which involve the emission of one or more particles.
4. The sequence of radiations emitted in the following radioactive process,

$_{Z+2}^{}\textrm{X}^{A}\to _{Z}^{}\textrm{Y}^{A-4}\to _{Z+1}^{}\textrm{Y}^{A-4}\to _{Z-1}^{}\textrm{K}^{A-8}$

is $\alpha-\beta -\alpha$.

Hence, option D is correct.
