WebJun 2, 2024 · A covalent bond is formed between two atoms by sharing electrons. The number of bonds an element forms in a covalent compound is determined by the number of electrons it needs to reach octet. Hydrogen is an exception to the octet rule. H forms only one bond because it needs only two electrons. Back to top. WebThere are two main types of chemical bonds: covalent bonds and ionic bonds. The definition of a covalent bond, is a bond where there are electron between the atoms that are shared fairly equally. The more equally they are shared, the more covalent character the bond has.
