Which of the following have their valence electrons in the same shell? Which of the following have their valence electrons in the same shell? N, As, Bi He, Ne, F B, Si, As Li, N, F

N, Ne, F, B, Li

Explanation:

Valence electrons are the electrons that are found in the outermost shell in a neutral atom. These five elements are the only one whose valence electrons fall on the same shell. The second shell. Their electronic configurations are as follows:

N: 2,5

Ne:2,8

F:2,7

B:2,5

Li: 2,3
