Answer:
An atom will be neutral if its protons and electrons are distributed equally. The atom develops charge and turns into an ion if there are more or fewer electrons than neutrons.
Step-by-step explanation:
Cadmium(Cd), has an atomic number of 48 and is found in group 12 of period 5 of the periodic chart. As a result, the nucleus of a neutral cadmium atom will be surrounded by a total of 48 electrons.
