When an atom gains a positive charge it either gains a proton or gains an electron
It could also lose one of them
Because the positive charge of the protons in an atom are cancelled out by the negative charges of the electrons in the atom.
For the atom to be neutral, the positive and negative charges must cancel each other out.
Protons contribute positive charges to atoms, while electrons contribute negative charges. An atom will have an overall positive charge if it has more protons than it does electrons. This most commonly occurs when an atom loses an electron or two, like what is common with alkaline and earth metals.
It means it has more protons (positive charge) and neutrons (no charge) than electrons (negative charge). This gives it an overall positive charge.
The nucleus of an atom contains the neutral neutrons and the positive protons. Negatively charged electrons orbit the nucleus.
Because the positive charge of the protons in an atom are cancelled out by the negative charges of the electrons in the atom.
If an atom has 3 positive charges (protons) and 4 negative charges (electrons), the 3 positive charges would "cancel out" 3 negative charges, with one negative charge left over. So the atom would have a charge of -1.

The atom gets negative charges and positive charges from other things.

The charges of an atom are, protons are positive (+). Neutrons has a neutral charge or no charge(0) and electrons have a negative charge (-).
Electrons contain negative charges, and protons contain positive charges.
protons
Neutral - the atom will have no charge.
none. they would explode if there were no positive with negative charges
