Why do metals of nonmetals form anions?
Answers:
You go by how close they are to the nearest inert thing. if they become isoelectronic and in doing so give up e-, they become positive cations, if they gain e-, they become unenthusiastic anions. specifically, metals become anions and nonmetals become cations
What is a metal of nonmetal? IF your talking about nonmetals, they form negatively charged anions because the nonmetals are on the right side of the intervallic table, meaning they have more electrons than metals. Since they almost own a full valence electron shell and they want 8 electrons in it, they tend to just steal and electron from a metal to realize a full valence shell of 8 electrons. For example, Chlorine has 7 electrons in its valence so it can effortlessly get 8 by stealing a electron from sodium, so it becomes and anion. Source(s): Chem class!
