What do you call an atom that has more protons than electrons?
Molecule
Isotope
Anion
Cation
A cation is an ion with positive charge, which means it has more protons (positively-charged particles) than electrons (negatively-charged particles). Cations are formed when an atom loses one or more electrons: the loss of the negatively-charged electron(s) results in an overall positive charge.
