Answer:

Atomic Number: 35

Number of Neutrons: 2

Explanation:

The number of protons and electrons are the same, so given that this element has 35 electrons, it also has 35 protons.

Atomic number is the number of protons, so it is 35.

Mass number is the number of protons + neutrons, so take the mass number of 37 and subtract the 35 protons to get 2 neutrons.

Why are ions usually formed during the interaction of metal with nonmetal and not between two metals? ​
Alik [6]

Explanation:

Ions are always formed when metals and non-metals interact because metals are electropositive. They willing release electrons to non-metals that are electronegative.

This activity results in charge separation. The transfer of electrons from one specie to another is what results in an ionic bond and the precedence of charged particles.

Between non-metals, the electrons are jointly shared. Therefore, there is no charge separation.
