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

Answer:
Ionic Bonding and Electron Transfer
An ionic bond results from the transfer of an electron from a metal atom to a non-metal atom.
Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another. This exchange results in a more stable, noble gas electronic configuration for both atoms involved. An ionic bond is based on attractive electrostatic forces between two ions of opposite charge.
Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion.
Ionic bonds differ from covalent bonds. Both types result in the stable electronic states associated with the noble gases. However, in covalent bonds, the electrons are shared between the two atoms. All ionic bonds have some covalent character, but the larger the difference in electronegativity between the two atoms, the greater the ionic character of the interaction.
