WebGraphite is a dark gray to black, very soft, shiny metallic mineral with a distinctive greasy feeling. One of the Earth’s softest minerals, graphite will easily leave marks on paper, which is why it is used for fine artist pencils. Even modern pencil ‘lead’ is composed of graphite mixed with clay. WebGraphite is a mineral which is composed entirely of the element carbon as are diamonds. Graphite and diamond have different molecular structures. In graphite each carbon atom has 4 valance electrons. Only 3 of these are used to bond (covalently) to the adjacent carbon atom, and so on through all the carbon atoms in a graphite structure.

WebDec 19, 2024 · Importantly, the layers in graphite are 'aromatic'. Rather than suggesting they smell nice, this means the atoms in a single layer have alternating single and double bonds (see diagram below). This doesn't only strengthen graphite's structure but allows electrons to move freely along the layers.
