Metals vs Non-Metals
Physical Properties Comparison
| Property | Metals | Non Metals |
|---|---|---|
| Physical State | Most metals are solids at room temperature except mercury which is a liquid. Gallium and Cesium also changes into liquid at slightly above room temperature. | Non Metals exist in all states. Eleven are gases, bromine is liquid while others are solids. |
| Melting and Boiling Point | Generally have high melting and boiling points. (Exceptions are Gallium, Mercury, Sodium and Potassium.) | Generally they have low melting and boiling points. Exceptions are: Carbon, Boron and Silicon. |
| Density | They have high density except Sodium and potassium. | Low denisty (Diamond is an exception.) |
| Lusture | Metals shine and are lustrous. | Non-metalls appear dull. (Exceptions are Diamond, graphite and iodine.) |
