WebAug 13, 2024 · Graphite has a giant covalent structure in which: there are no covalent bonds between the layers. there is one non-bonded – or delocalised – electron from each atom. Is graphite powder ionic or covalent? As a result, graphite exhibits properties typical of both covalent and molecular solids. WebJun 21, 2024 · Pi bonds are made by the overlap of two unhybridized p orbitals. Lone pair electrons are usually contained in hybrid orbitals. The hybrid orbitals used (and hence the hybridization) depends on how many electron groups are around the atom in question. An electron group can mean either a bonded atom or a lone pair.
