The answer is atoms are held to each other in compounds by chemical bonds. That was where chemistry started :)

Protons are like charges - they REPEL each other

My grandson is the goalie, no waiting in this matter :)
So the answer is chemical bonds? I'm sure someone can take it for you.
now when the Na gives up an electron, it has more protons than electrons and is a POSITIVE ion

when the chlorine grabs that electron to complete its outer shell it has one more electron than proton and is a NEGATIVE ion because electrons are negative.

Since positive charges and negative charges attract each other, we get salt.
Yes, chemical
one is ionic, the other covalent but both are CHEMICAL
