59. State any five physical properties of metals and five physical properties of non-metals. Solution: Properties of Metals: 1. Metals are ductile 2. Metals are malleable 3. Metals are good conductor of electricity 4. They are lustrous 5. They are hard in nature 3.

Metallic Bonding and the Physical Properties of Metals …

Physical Properties of Metals: High Melting Point. In general, metals have high melting and boiling points because of the strength of the metallic bond. The strength of the metallic bond depends on the: nuer of electrons in the delocalised ''sea'' of electrons.

atomic and physical properties of period 3 elements

1/5/2021· Silicon has high melting and boiling points because it is a giant covalent structure. You have to break strong covalent bonds before it will melt or boil. Because you are talking about a different type of bond, it isn''t profitable to try to directly compare silicon''s melting and boiling points with aluminium''s.
