To which group does nitrogen (at. no. 7) belong in the periodic table?

Explanation

To determine the group to which nitrogen (atomic number 7) belongs in the periodic table, we can follow these steps:

### Step 1: Write the Electronic Configuration
First, we need to find the electronic configuration of nitrogen. The atomic number of nitrogen is 7, which means it has 7 electrons. The electronic configuration can be written as follows:

- The first two electrons fill the 1s orbital: **1s²**
- The next two electrons fill the 2s orbital: **2s²**
- The remaining three electrons go into the 2p orbital: **2p³**
