An isotope contains 16 protons 18 electrons and 16 neutrons. what is the identity of the isotope

Sulfur ₁₆S³²

Explanation:

The sulfur have sixteen protons sixteen neutrons and sixteen electrons. The sum of neutrons and protons is equal to atomic mass. So the given element have sixteen protons and sixteen electron, the atomic mass would be 32 and the element with atomic mass 32 is sulfur.

The number of electrons are equal to the number of protons. In the given element two electrons are more than number of protons. It means element gain two extra electron from another element and it is present in ionic form.

It is present in given form:

S²⁻

Electronic configuration:

S₁₆ = [Ne] 3s² 3p⁴

To complete the octet sulfur gain two electrons from other element and get stable.
