Metallic Bonding occurs with a ( lattice, group, sea ) of metal ( atoms, ions ) surrounded by a sea of ( delocalised, free, negatively charged ) electrons. The same applies for ( metal oxides, metallic compounds, alloys ), however there will be at least 2 different types of metal ion in the ( lattice, sea, group ). Electrons can become ( delocalised, bonded, lost ) easily because metals have ( few, many, no, 6 ) electrons in their ( outer, inner, intermediate ) shells.
