An electron is a sub-atomic particle, not an atom. But it is electrically charged (it has a charge of minus one). The simplest atom, the hydrogen one isotope, has just one proton and one electron. An...
Protons are positively chargedElectrons are negatively chargedand Neutrons have a neutral chargethe number of protons and neutrons are equal so the atom has no overall charge
An atom is neutrally charged particle. This is because an atom contains equal number of protons[+ve] and electrons[-ve] which balance out to give a nuetal charged.Charged atoms are called IONs.
