검증된 단계별 안내1
Understand that cations are positively charged ions formed when an atom loses one or more electrons.
Recall that metals tend to lose electrons easily due to their low ionization energies, making them likely to form cations.
Recognize that nonmetals and halogens typically gain electrons to form anions (negatively charged ions), not cations.
Note that noble gases are generally inert and do not commonly form ions because they have a full valence shell.
Conclude that metals are the type of elements that typically form cations.
