Question

What must be true if an atom is ionized?

Select one:
a. It must be radioactive
O b. It must have different numbers of protons and neutrons
O c. It must have an electron that has jumped to a higher energy
level
O d. It must have different numbers of protons and electrons

Answer 1

I think it’s D.

Step-by-step explanation:

An atom does not have a different amount of protons and electrons if there is no change... During ionisation you either lose or gain electrons, so when that happens (a change) it will have a different number.
