bond characterized by the transfer of electrons from one atom to another ionic bond
type of chemical bond present between atoms in such substances as calcium bromide and sodium chloride ionic bond
bond characterized by sharing of valence electrons with many neighboring atoms, forming a cloud or sea of delocalized electrons permeating he substance metallic bond
type of bond that tends to produce solids that are malleable and ductile metallic bond
bond characterized by sharing one or more electron pairs between two atoms covalent bond
