Any ion.
If there is an imbalance in the numbers of protons in electrons, then yes, an atom would have electrical charge.
A neutral atom hasn't an electrical charge.
A fluorine atom has a negative electrical charge of -1 due to its 9 protons and 10 electrons.
Neutron .
The atom is neutral,, there is no net charge
Gained or lost electron(s).
A beryllium atom without electrical charge.
electron
The electrical charge depends on electrons.
Neuton does not have any charge
A "normal" atom has not an electrical charge; ions have a charge.
The proton is the particle that has a positive charge. The neutron is the particle that has a neutral charge. both of these reside in the nucleus of an atom.
