Question

calculate the valency for the following atoms: c) Atom with atomic number 16 please answer​

Answer 1

Answer:

Valency is 2

Explanation:

Electronic configuration of element

2,8,6

So valence electrons = No of electrons in outer shell

So valency for atoms with more than 4 atoms in outer shell 8-no of valence electrons

8-6

2 = Valency

Extra

As it will gain 2 electrons there will be 16 protons and 18 electrons So the charge of atoms will be 2-

Atom is Oxygen
