Name any two elements of group one and write their electronic configurations. What similarity do you observe in their electronic configurations? Write the formula of oxide of any of the aforesaid element

Explanation

**Step-by-Step Solution:**

1. **Identify Two Elements of Group One:**
- Group one elements are known as alkali metals. Two common elements from this group are Sodium (Na) and Potassium (K).

2. **Write Their Electronic Configurations:**
- Sodium (Na) has an atomic number of 11. Its electronic configuration is:
- 1s² 2s² 2p⁶ 3s¹, which can be simplified to [Ne] 3s¹ (where [Ne] represents the noble gas Neon).
