Question

If no.of es=8,no.of protons =8 and no.of neutrons = z in atoms of an element × state its atomic no,valency,atomic mass, atomic representation

Answer 1

Given

$no. \: of \: {e}^{ - } = 8 \\ no. \: of \: {p}^{ + } = 8 \\ no. \: of \: {n}^{0} = ? \:$

Thus the atomic no. of the element = 8

and so the element is

$_{8}{O}^{16}$

atomic mass = 16

valency = -2

The atomic representation is rough so extremely sorry for that.
