Question

In an anion :-
(1) Number of proton decreases
(2) Protons are more than electrons
(3) Effective nuclear charge is more
(4) Radius is larger than neutral atom​

Answer 1

Explanation:

Option 4

Radius is larger than neutral atom

Hope u understand

Answer 2

Answer: In an anion, radius is larger than neutral atom.

Explanation:

• A negative charged ion is called an anion.

• It is negatively charged, therefore, it has more electrons than protons.

• Anion is formed because of accepting electrons. Hence, the number of protons in neutral atom and anion is same. The number of electrons increases which gives rise to negative charge.

• Because of accepting electron, the effective nuclear charge decreases.

• Repulsion between electrons increases because of the increase in number of electrons. It becomes difficult for the same nucleus to hold on to more number of electrons, which leads to increase in radius.
  Hence, radius of anion > radius of neutral atom.
