Some elements can make ions when what event occurs? Question 8 options: The gain of an electron The loss of a neutron The gain of a neutron The gain of a proton

The gain of an electron.

Explanation:

Ions are made when an atom does no longer have an equal number of protons and electrons.

This would theoretically mean that in order for an atom to become an ion, it would have to either gain or lose an electron or a proton.

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.
