Question

tyler dewitt-17min) multiple-choice question 14. how many valence electrons does nitrogen have? five four three rewatch

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: Identify the valence shell

The valence shell is the outermost shell. For Nitrogen, the outermost shell is the second shell (\(n = 2\)).

Step3: Count the valence electrons

In the second shell (\(n=2\)), there are \(2s^{2}2p^{3}\). The sum of electrons in the \(2s\) and \(2p\) sub - shells is \(2 + 3=5\). So Nitrogen has 5 valence electrons.
