The electronic configurations of a few elements are listed:
(i) `1s^(2) 2s^(2) 2p^(6) 3s^(2)`
(ii) ` 1s^(2) 2s^(2) 2p^(5)`
(iii) `1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^2`
(iv) ` 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6)`
(v) ` 1s^(2) 2s^(2) 2p^(6), 3s^(2) 3p^(6) 3d^(10) 4s^1`
(vi) ` 1s^(2) 2s^(2) 2p^3`
From the above electronic configuration predict which one is
(a) a halogen (b) noble gas element (c) an alkaline earth element (d) present in group 14 (e) a transition metal (f) a member of group 15

Explanation

To solve the problem of identifying the elements based on their electronic configurations, we will analyze each configuration step by step and determine which category each element belongs to.

### Step-by-Step Solution:

1. **Identify the Electronic Configurations**:
- (i) `1s² 2s² 2p⁶ 3s²`
- (ii) `1s² 2s² 2p⁵`
- (iii) `1s² 2s² 2p⁶ 3s² 3p²`
