Give the electronic configureation and geometrical representation of the following element ? Sodium.

Explanation

### Step-by-Step Solution for Sodium's Electronic Configuration and Geometrical Representation

**Step 1: Identify the Atomic Number and Mass Number of Sodium**
- The atomic number of sodium (Na) is 11. This means sodium has 11 protons.
- The mass number of sodium is 23, which is the total number of protons and neutrons.

**Step 2: Calculate the Number of Neutrons**
- To find the number of neutrons, subtract the atomic number from the mass number:
