Questions: Nitrogen (N) has atomic number of 7. How many electrons are in its 1st shell?

Solution Steps

The atomic number of an element indicates the number of protons in its nucleus, which is equal to the number of electrons in a neutral atom. For nitrogen (N), the atomic number is 7, meaning it has 7 electrons.

Electrons are arranged in shells around the nucleus. The first shell can hold a maximum of 2 electrons, and the second shell can hold up to 8 electrons.

Since nitrogen has 7 electrons:

• The first shell will be filled with 2 electrons.
• The remaining 5 electrons will go into the second shell.
