Which of the following is the best description of how electrons are transferred in an ionic bond?

The answer which is the best description of how electrons are transferred in an ionic bond is - A metal atom loses electrons and a nonmetal atom gains electrons. While forming an ionic bond the metal atom loses electrons to gain a positive charge whereas the non-metal atom gains these electrons and gets a negative charge and then these charges attract and they bond together forming the ionic bond.
