Question

name two elements that have 7 electrons in their Valence shell?

​

Answer 1

Answer:

Halogens have 7 atoms in their Valence shell.

1) Fluorine (F)

2) Chlorine (Cl)

Answer 2

Chlorine and Fluorine are the two elements which have 7 electrons in their valence shell.

Electronic configuration :-

1) Chlorine → No. of electrons = 17

Therefore, E.C. = 2,8,7

2) Fluorine → No. of electrons = 9

Therefore, E.C = 2,7
