Using molecular orbital diagram, arrange the following molecular species in the increasing order of their stabilities:
` H_2 ,H_(2)^(+) and H_(2)^(-)`

Explanation

To arrange the molecular species \( H_2 \), \( H_2^+ \), and \( H_2^- \) in increasing order of their stabilities using molecular orbital theory, we will follow these steps:

### Step 1: Understand the Molecular Orbitals
- Each hydrogen atom has one electron in its \( 1s \) orbital. When two hydrogen atoms combine, they form molecular orbitals: a bonding molecular orbital (\( \sigma_{1s} \)) and an anti-bonding molecular orbital (\( \sigma^*_{1s} \)).

### Step 2: Determine the Electron Configuration
1. **For \( H_2 \)**:
- Total electrons = 2 (1 from each hydrogen)
