40К-----------19 ------------21 ------------19

Answer 3

Isotopes of Argon:

Argon has three naturally occurring isotopes: ^36^Ar, ^38^Ar, and ^40^Ar. Let's determine the number of protons, neutrons, and electrons for the isotopes ^39^Ar and ^40^Ar.

Number of Protons, Neutrons, and Electrons:

- ^39^Ar: - Protons: 18 - Neutrons: 21 - Electrons: 18 - The isotope ^39^Ar has 18 protons, 21 neutrons, and 18 electrons [[1]].

- ^40^Ar: - Protons: 18 - Neutrons: 22 - Electrons: 18 - The isotope ^40^Ar has 18 protons, 22 neutrons, and 18 electrons [[2]].

These isotopes have different numbers of neutrons, resulting in their distinct atomic masses.
