WebAtomic carbon has six electrons: two inner shell (core) electrons in the 1 s orbital, and four valence (outer most shell) electrons in the 2 s and 2 p orbitals. Electron Configuration for Bonded Carbon When bonded with a full octet (such as in methane ) carbon has eight valence electrons (two per covalent bond ). WebThe term valence refers to the ability of an element to form bonds with other atoms. An element’s valence was historically determined by how many hydrogen atoms it could bond to (which is determined by how many valence electrons it has available for bonding): for example, carbon can form CH 4 so it has a valence of 4, and 4 valence electrons. On …
