Answer:
1. Protons
Explanation:
In a neutral atom, the number of electrons equals the number of protons within the atom.
Protons are the positively charged particles
Electrons are the negatively charged particles
Neutrons do not carry any charges.
Therefore, the number of protons and electrons in a neutral atom is the same and this leaves a net zero charge on the atom.
Ions usually have varied number of protons and electrons.
