Question

The electronic configuration of three elements are given below:
E(2,8,8,1); F(2,6); G(2,8,7)
(i) represent the molecule of F by dot diagram
(ii) write down the formula of compound formed between E and G
(iii) clarify the elements E, F, and G as metals and non metals​

Answer 1

a metal has (1,2,3,4) electrons in the outer shell and a non metal has (5,6,7,8) electrons in the outer shell! also e and g as a compound wont have any valence thing because they have the exact number of electrons that can be shared to complete the octet state (8 electrons)

Answer 2

ii). KCl

iii). E = potassium

F= oxygen

G= Chlorine
