The answer is D) a neutron.
When we say an atom's mass is, like 5 atomic mass units actually we are saying that the total number of the neutrons and protons in its nucleus is 5.
The mass of a neutron and a proton is each one atomic mass unit.
Mass of a neutron is approximately 1 atomic mass unit.
H. The atom would no longer be aluminum
If you added a proton to an atom of aluminum it would become a silicone ion
I'm happy to help but do you have the options?
