Answer:
I, II, III,IV
Explanation:
Metals are known to possess metallic bonds. In a metallic bond, electro-positive metals loose electrons which form a cloud of electrons which exerts an attractive force on the positive metallic ions. This attractive force holds the metal atoms together in the crystal lattice.
The physical properties of metals include;
I. thermal conductivity
II. electrical conductivity
III. malleability
IV. ductility
Hence, substances that exhibit properties I-IV are metals and have metallic bonds.
The following properties which a substance that has metallic bonding
normally have include
- thermal conductivity
- electrical conductivity
- malleability
- ductility
Metals are elements which have metallic bonding which is always strong as
it helps to form a lattice.
Metals are good conductors of heat and electric current , they can also be
bent in to different shapes . This means it has all the properties listed above.
