Answer #1

The number of electrons as indicated by the electronic configuration of the atom is equal to the number of protons in the atom , which determines the atomic number / identity of the element .

A) Since here the number of electrons is 18 . So The element will be Argon represented as Ar

B) Since here the number of electrons is 19. So the element will be Potassium represented as K

C) Since here the number of electrons is 26. So the element will be Iron represented as Fe

D) Since the number of electrons is 36. So the element will be Krypton represented as Kr
