Write the group and period numbers of oxygen from its electronic configuration (O = 8 = 2, 6).

Explanation

To find the group and period numbers of oxygen from its electronic configuration, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Electronic Configuration**:
- Oxygen (O) has an atomic number of 8, which means it has 8 electrons. The electronic configuration of oxygen is given as 2, 6. This means that there are 2 electrons in the first shell (K shell) and 6 electrons in the second shell (L shell).

2. **Determine the Number of Valence Electrons**:
...
