Question

In which region of the periodic table would an element with the electron configuration below be located?

1s2,2s2,2p6,3s2,3p5

Answer 1

The answer is halogens

Answer 2

This element lie in the region of HALOGENS.

Explanation:

The element with the electron configuration 1s2,2s2,2p6,3s2,3p5 is Chlorine(Cl)

" Chlorine is a chemical element with symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature "
