ionic bonding

Which statement describes a step in the formation of an ionic bond? An attraction occurs between two ions that have the same charge. A metal atom forms a cation, and a nonmetal atom forms an anion. A more electronegative atom transfers electrons to a less electronegative atom. A metal pulls electrons from another metal and produces a force of attraction.

A metal atom forms a cation, and a nonmetal forms an anion

The diagram below shows the atoms involved in forming table salt. Which statement best describes what happens next? Sodium becomes an anion by losing an electron to chlorine. Chlorine becomes a cation by losing an electron to sodium. Sodium becomes a cation by gaining an electron from chlorine. Chlorine becomes an anion by gaining an electron from sodium.

Chlorine becomes an anion by gaining an electron from sodium
