How many dots does the electron-dot diagram of nitrogen have?
A
5
B
15
C
7
D
3
Explanation: 

Detailed explanation-1: -This shows 5 dots around the symbol of nitrogen. These five dots represent the five electrons that are located in the valence shell of nitrogen.

Detailed explanation-2: -Two Nitrogen atoms share six electrons (three pair of electrons) and form triple bond. These bonds are written as straight line. Four valence electrons remain after bonding in the molecule. Hence each Nitrogen atom contains a non bonding pair represented as dots.

Detailed explanation-3: -The nitrogen atom has five electron present in 2s and 2p subshell and these electrons are called valence electrons.

Detailed explanation-4: -Nitrogen is found to have either 3 or 5 valence electrons and lies at the top of Group 15 on the periodic table. It can have either 3 or 5 valence electrons because it can bond in the outer 2p and 2s orbitals.
