Question

Given that oxygen-16 and oxygen-18 both have an atomic number of 8, how many electrons, protons, and neutrons do these oxygen atoms contain?

A) These oxygen configurations contain the same number of subatomic particles - 8 electrons, 6 protons and 10 neutrons.
B) Any oxygen atom contains 8 electrons and 9 neutrons but these vary in the number of protons - 8 and 10 respectively.
C) The oxygen allotropes contain 8 electrons but each contains a different number of neutrons and protons - 8 and 10 respectively.
Eliminate
D) Both oxygen isotopes contain 8 electrons and 8 protons but each contains a different number of neutrons - 8 and 10 respectively.

Answer 1

D

Step-by-step explanation:

Both oxygen isotopes contain 8 electrons and 8 protons but each contains a different number of neutrons - 8 and 10 respectively.

Oxygen-16 and Oxygen-18 are isotopes where they have the same number of protons and electrons, but the number of neutron varies.
