Question

2 fill in the blank 2 points ions differ by the number of choose your answer... isotopes differ by the number of choose your answer...

Explanation:

For the first blank (ions): Ions are atoms or molecules with a net electric charge, which comes from a difference in the number of electrons (gaining or losing electrons). For the second blank (isotopes): Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons, so they differ by the number of neutrons.

Answer:

First blank: electrons
