Figure 2.12, Hydrogen and Oxygen with covalent bond
Example 2: Covalent Bonding Methane (C4H)
Carbon is non-metal in a solid form and has four electrons valence. Hydrogen is also a non-
metal, in gas form and has one electron in the outer shell. To complete their outer shells both
hydrogen and carbon needs 4 more electrons. So, 4 atoms hydrogen sharing as show in Figure
2.13, their atoms with carbon to complete their both outer shell electrons which is eight.
