Answer
C & D
Reason — The electronic configuration of six atoms is given below :
| Atom | Electronic configuration | Valence electrons |
|---|---|---|
| A | 2, 5 | 5 |
| B | 2 | 2 |
| C | 2, 6 | 6 |
| D | 2, 8, 6 | 6 |
| E | 2, 8, 8 | 8 |
| F | 2, 8, 3 | 3 |
Atom C (2,6) and D (2,8,6) both have 6 valence electrons. So, they both belong to Group 16.
