The bond order of ` N_(2), N_(2)^(+) , N_(2) ^(-) and N_(2)^(2-)` respectively are ……….., ………….. ,………….. and …………… .

Explanation

To find the bond order of \( N_2 \), \( N_2^+ \), \( N_2^- \), and \( N_2^{2-} \), we will follow these steps:

### Step 1: Determine the total number of electrons for each species.
- For \( N_2 \): Each nitrogen atom has 7 electrons, so \( N_2 \) has \( 7 + 7 = 14 \) electrons.
- For \( N_2^+ \): This species has lost one electron, so it has \( 14 - 1 = 13 \) electrons.
- For \( N_2^- \): This species has gained one electron, so it has \( 14 + 1 = 15 \) electrons.
- For \( N_2^{2-} \): This species has gained two electrons, so it has \( 14 + 2 = 16 \) electrons.
