Answer:

Solution :

Lithium

Z = 3

P = 3

E = 3 = (2, 1) p=3

A = 7 n=4

P + n = A

3 + n = 7

N = 4



Carbon

Z = 6

P = 6

E = 6 = (2, 4) p=6

A = 12 n=6

P + n = A

6 + n = 12

N = 6

Wewaii [24]
Ba₃(PO₄)₂ is a compound made of a metal cation and polyatomic ion. 
polyatomic ion is when 2 or more atoms are covalently bonded together and together have a charge and can act as one compound that can bond with another atom. 
In this case Ba²⁺ is the metal cation and PO₄³⁻ is the polyatomic ion. this is called the phosphate ion. one phosphate atom is bonded to 4 O atoms with an net charge of -3 and acts as a single unit.
