Answer to Question #30908 in Organic Chemistry for wasim

Question #30908
why the size of anion greater then anion explain with example
Expert's answer
When an atom gains an electron, it becomes a negatively charged ion that we call an anion. Anions are larger in size than their parent atoms because they have one or more additional electrons. When an atom loses an electron, it becomes a positively charged ion called a cation. Cations are smaller than their parent atoms because they have lost electrons.

Example:

Na + e- ==> Na- anion
Na - e- ==> Na+ cation

Na+ < Na < Na-
