Question

1. how many electrons reside in s subshells in nitrogen? how many reside in p subshells?

Explanation:

Step1: Determine the electron configuration of nitrogen

Nitrogen has an atomic number of 7. Its electron configuration is \(1s^{2}2s^{2}2p^{3}\).

Step2: Count electrons in s subshells

The \(1s\) subshell has 2 electrons and the \(2s\) subshell has 2 electrons. So, total electrons in s subshells: \(2 + 2=4\).

Step3: Count electrons in p subshells

The \(2p\) subshell has 3 electrons.

Answer:

4 electrons reside in s subshells and 3 electrons reside in p subshells.
