WebHydrogen can participate in either ionic or covalent bonding. When participating in covalent bonding, hydrogen only needs two electrons to have a full valence shell. As it has one electron to start with, it can only make one covalent bond. Similarly, boron has 3 electrons in its outer shell.

WebApr 7, 2024 · Covalent bonds are formed between non-metallic elements like hydrogen, oxygen, etc. Covalent bonding does not result in the formation of new electrons. The bond only pairs them. Covalent bonds include single, double, or triple bonds where 2, 4, or 6 electrons are shared respectively. There exist very powerful chemical bonds between … WebA covalent bond is a shared pair of electrons. Covalent bonding results in the formation of molecules or giant structures.
