Question
Which is greater in size an atom or an anion?
Advertisements
Solution
An anion is greater than an atom since it is formed by the gain of electrons, and so the number of electrons is greater than the number of protons. The effective positive charge in the nucleus is less, so less inward pull is experienced. Hence, the size expands.
