For the formation of an ionic bond between two atoms, one atom should have …………….. And the other atom should have …………

Explanation

To answer the question regarding the conditions necessary for the formation of an ionic bond between two atoms, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding Ionic Bonds**: An ionic bond is formed when one atom transfers electrons to another atom. This typically occurs between a metal and a non-metal.

2. **Characteristics of the Metal Atom**: For the formation of an ionic bond, the metal atom must have a low ionization energy. This means that it can easily lose one or more of its electrons to become a positively charged ion (cation).
