The electronic configuration of two elements A and B are 2, 8, 2 and 2, 6 respectively. What is the compound formed when they combine?

Explanation

To determine the compound formed when elements A and B combine, we will follow these steps:

### Step 1: Identify the Elements
- The electronic configuration of element A is 2, 8, 2.
- The electronic configuration of element B is 2, 6.

### Step 2: Determine the Nature of the Elements
- Element A has 2 electrons in its outermost shell (valence shell), which indicates that it is likely a metal (specifically, it is in Group 2 of the periodic table).
