An element X belongs to the third period of the p- block elements. It has 4 electrons in the outermost shell. Name the element.

Explanation

To determine the element X that belongs to the third period of the p-block elements and has 4 electrons in its outermost shell, we can follow these steps:

### Step 1: Identify the period and block
- The question states that the element X is in the third period and belongs to the p-block.
- The third period includes the elements from sodium (Na) to argon (Ar).

**Hint:** Remember that the period number indicates the highest principal energy level (n) of the electrons.
