WebThe more electrons that are shared between two atoms, the stronger their bond will be. As an example of covalent bonding, let’s look at water. A single water molecule, \text H_2\text O H2O, consists of two hydrogen … WebThe term graphene was coined using the prefix “graph” taken from graphite and the suffix “-ene” for the C=C bond, by Boehm et al. in 1986. The synthesis of graphene can be done using various methods. The synthesized graphene was further oxidized to graphene oxide (GO) using different methods, to enhance its …
