What is the atomic number of the element having maximum number of unpaired `2p` electrons? To which group it belongs?

Explanation

To find the atomic number of the element with the maximum number of unpaired 2p electrons and to determine its group, we can follow these steps:

### Step 1: Understand the 2p Orbital
The 2p subshell can hold a maximum of 6 electrons, distributed among three orbitals (2p_x, 2p_y, and 2p_z). Each orbital can hold 2 electrons, but we are interested in unpaired electrons.

### Step 2: Determine Maximum Unpaired Electrons
For maximum unpaired electrons in the 2p subshell, we can have 3 unpaired electrons. This occurs when each of the three 2p orbitals contains one electron each, which is represented as 2p^3.
