A. it decreases
B. it increases
C. it remains the same
D. it is impossible to tell unless you know the specific element

Answer 1

Answer: option B. it increases.

An anion is a negative ion.

To become an anion a non-metal gains one or more electrons.

When the atoms gain electrons and form anions, they always become larger. This is due to the fact that the addition of an electron increases the electrostatic repulsion force between the outer electrons of the atom making them to get apart and, in consequence to occupy more space.
