WebCarbon has 4 valence electrons, and its electron configuration is 1s^2 2s^2 2p^2. Now, in order for carbon to bond appropriately 4 times you could promote an electron from the 2s orbital to the 2p orbital (thus giving you 2s^1 and 2p^3). WebOne of the most useful properties of graphene is that it is a zero-overlap semimetal (with both holes and electrons as charge carriers) with very high electrical conductivity. Carbon …
Graphene is a single layer (monolayer) of carbon atoms, tightly bound in a hexagonal honeycomb lattice. It is an allotrope of carbon in the form of a plane of sp2-bonded atoms with a molecular bond length of 0.142 nanometres.
