[Metals generally have lower electronegativities than do nonmetals. Thus, metal atoms attract electrons less strongly and tend to lose electrons to acquire an octet (noble gas electron configuration). Nonmetals tend to gain electrons and form negatively-charged ions (anions).
Also to know is, are metal cations or anions?
Positive and Negative Ions: Cations and Anions. Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The alkali metals (the IA elements) lose a single electron to form a cation with a 1+ charge.
Why do metal atoms tend to form cations?
Anions are negatively charged ions and cations are positively charged ions. 2) Anions tend to be __________ and cations tend to be __________. Nonmetals tend to gain electrons and form anions, metals tend to lose electrons and form cations.
Why are almost all metals tend to form cations?
An atom that loses one or more electrons forms a cation ion. An atom that gains one or more electrons forms an anion ion. Atoms lose or gain electrons to match the valence-electron configuration of a noble gas. Explain why most all metals tend to form cations.
