Question

When a radioactive element emits an electron, the daughter element formed will have:

A
Mass number one unit less
B
Atomic number one unit less
C
Mass number one unit more
D
Atomic number one unit more
Solution
Verified by Toppr

Correct option is D. Atomic number one unit more
A beta particle is an electron emitted by a radioactive nucleus. In beta decay, one of the neutrons in the nucleus suddenly changes into a proton, causing an increase in the atomic number of the parent element.
$$_z A^m \rightarrow \ _{z + 1} B^m + \ _{-1} e^0$$

Hence, option $$D$$ is correct.
