On the basis of electron affinity, comment on the resemblance of hydrogen with halogens.

Explanation

### Step-by-Step Solution:

1. **Understanding Electron Affinity**:
- Electron affinity refers to the amount of energy released when an atom in the gas phase gains an electron to form a negative ion. Higher electron affinity indicates a greater tendency to gain an electron.

2. **Electronic Configuration of Halogens**:
- Halogens have the electronic configuration of \( ns^2 np^5 \). For example, Chlorine (Cl) has the configuration \( [Ne] 3s^2 3p^5 \).
- This configuration indicates that halogens have seven valence electrons and require one more electron to achieve a stable noble gas configuration (like Neon).
