Diamonds are a crystal form of pure carbon (C). The carbon atoms of a diamond are connected in a very compact and structured way. The carbon atoms found in graphite (in pencils) have a different crystalline arrangement. According to the Mohs hardness scale, diamonds are very hard with a value of 10 while graphite is very soft with a value of 1.5.

Properties Of Matter Hardness And Softnesstransparency

These properties help us to recognise them. We touch a material, see its color, smell it and thereby recognise it. The features which help us to recognise a particular material are called properties of the material. 1. Hardness and softness: Some materials are hard and some are soft. Stone is hard while clay and plastic are soft.
