Nitrogen atom has atomic number 7 And oxygen has atomic number `8` calculate the total number of electrons in nitrate ion

Explanation

To calculate the total number of electrons in the nitrate ion (NO₃⁻), we can follow these steps:

### Step 1: Identify the atomic number of nitrogen and oxygen
- The atomic number of nitrogen (N) is 7.
- The atomic number of oxygen (O) is 8.

### Step 2: Determine the number of nitrogen and oxygen atoms in the nitrate ion
- The nitrate ion (NO₃⁻) contains:
