WebCarbon forms unusually strong C-C single bonds, C=C double bonds, and carbon-carbon triple bonds. 2. The electronegativity of carbon ( EN = 2.55) is too small to allow carbon to form C 4- ions with most metals and too large for carbon to form C 4+ ions when it reacts with nonmetals. Carbon therefore forms covalent bonds with many other elements. 3. WebUnder certain conditions, a single carbon atom can combine with 4 hydrogen atoms. In this particular compound, carbon has four bonds, one to each of four hydrogen atoms. The compound, a gas, is called methane, CH4. Methane is a major component of natural gas.
