WebFor example, in methane (CH _4 4 ), carbon forms covalent bonds with four hydrogen atoms. Each bond corresponds to a pair of shared electrons (one from carbon and one from hydrogen), giving carbon the eight electrons it needs for a full outer shell. Hydrocarbons Hydrocarbons are organic molecules consisting entirely of carbon and hydrogen. WebAug 8, 2024 · Answers. Covalent bonds are formed by two atoms sharing electrons.

WebMay 28, 2016 · Based on the given model of ammonia, three covalent bonds are represented. • A bond, which is formed by sharing pair of electrons is known as the … WebWell, the oxygen atom in the water molecule has 2 lone pairs of electrons (electrons that are not shared with other atoms). These electrons push away the bonded pairs of electrons,giving it its "V shape". In the case of carbon dioxide,however,the carbon atom has no lone pairs so there is no repulsion between the bonded pairs and lone pairs. id theft credit repair
