Question

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

Answer 1

The gain of an electron.

Step-by-step 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.

• However, protons are located in the nucleus, so the energy required to add or remove a proton is immensely higher than the energy required to add or remove an electron.
