Carbon electron configuration: 1s22s22p2 Carbon is the element that I have chosen for this post. Carbon has 4 valence electrons and they reside in n=2 shell, specifically the 2s and 2p orbitals. Carbon has 2 unpaired electrons from the 2p orbital. Carbon can form 4 covalent bonds. Carbon can participate in double and triple bonds because it can share 1, 2, or 3 pairs of electrons when bonding. The number of valence electrons in Carbon allows it to share the pairs of electrons with another Carbo...
