Will give Brainliest! Can you answer fast?!? According to Dalton's atomic theory, which of the following best describes an atom?

Can be destroyed
Present in all matter
Composed of elements
Does not contain particles

Acertain atom has 22 protons and 19 electrons. this atom loses an electron. the net charge on the atom is now 4+1+01-4-. if this same atom with 22 protons and 19 electrons were to gain 3 electrons, the net charge on the atom would be 3+2+02-3-.
