When a neutral atom is converted into cation, there is:

Aa decrease in atomic number
Bin an increase in atomic number
Ca decrease in size
Correct Answer
Dan increase in size

Solution

When a neutral atom is converted into cation more effective nuclear charge experienced by electrons . Size is inversely proportional to effective nuclear charge . Thus size of a cation is less than the neutral atom.
