Chemistry AQA GCSE Bonding and Structure. 54 terms. YeboahShawnDGS. WebAs you write, flakes of graphite are broken off the pencil lead and stick to the paper. The other important difference between diamond and graphite is that graphite conducts electricity, unlike diamond. Each carbon atom in graphite makes three covalent bonds in the layer. That means there is a spare, delocalised bond which sits between the layers. journal of thermal analysis and calorimetry分区

"WebAQA GCSE Chemistry (Combined Science) Unit 2: Bonding, Structure and Properties of Matter The three states of matter are solid, liquid and gas. For a substance to change from one state to another, energy must be transferred. The particles gain energy. This results in the breaking of some of the attractive forces between particles during melting. " - Properties of graphite gcse aqa
