Explanation:
Atoms having a valence of electron of 1 or 2 are metals. They belong to the first and second group on the periodic table.
In metallic bonds, atoms of metals and alloys joins together.
- The formation of this type of bond is favored by the low ionization energy and a large number of electrons in the valence shells.
- The bond is an attraction between the positive nuclei of all closely packed atoms in the lattice and the electron cloud jointly formed by all the atoms losing their outermost shell electrons.
- Most physical properties of metals can be accounted for by this type of bonding.
