Question

Give four differences between metals and non-metals with reference to their

(a) Melting point and boiling point,

(b) Conductivity of heat and electricity,

(c) Malleability

(d) Solubility

Answer 1

| | Metals | Non-metals |
| (a) Melting point and boiling point, | Metals have both high melting point and boiling point. | Non-metals have both low melting and low boiling point. |
| (b) Conductivity of heat and electricity | They are good conductors of heat and electricity. | Non-metals are bad conductors of heat and electricity. |
| (c) Malleability | Metals are usually malleable. | All non-metal are non- malleable. |
| (d) Solubility | Metals are generally insoluble in water and other organic solvents. | They are both soluble and insoluble. |
