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

2b2t

explanation:

2b2t

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
