Which statement describes the valence electrons in metallic bonds? They are shared equally between two atoms.
They are shared unequally between two atoms.
They are shared among many atoms.
They are transferred from one atom to another.

The correct answer is D. During the formation of an ionic bond, the valence electrons are transferred from a metal atom to the non-metal atom, leading to the formation of an ionic bond. The atoms which lose valence electron, become positively charged, and the one which accepts it, becomes negatively charged.

consider the reaction below.
