Explain quantitatively the order of magnitude difference between the diamagnetic susceptibility of `N_2(-5xx10^-9)` (at STP) and `Cu(-10^-5)`.

Explanation

To explain quantitatively the order of magnitude difference between the diamagnetic susceptibility of nitrogen (N₂) and copper (Cu), we will follow these steps:

### Step 1: Identify the Given Values
- The diamagnetic susceptibility of nitrogen (N₂) is given as:
\[ \chi_{N_2} = -5 \times 10^{-9} \]
- The diamagnetic susceptibility of copper (Cu) is given as:
