8. Non-Metals Have Comparatively Low Melting Points and Boiling Points
(except graphite which is a non-metal having a very high melting point). This means that non-metals melt and vaporise at comparatively low temperatures. For example, sulphur is a non-metal having a low melting point of 119°C. Only one non-metal graphite has a very high melting point (of 3700°C). The majority of non-metals have very low boiling points due to which they exist as gases at room temperature.
