What is the valency of hydrogen?
Answer: The correct answer is 1.
Hydrogen is an element which has a valency capacity of 1. This has a close relation with the chemical behaviour of hydrogen especially in compound formation. This single valency electron is lodged in the hydrogen’s 1s, which is the only and also the outermost shell that the atom holds. Hydrogen is recognized as the simplest element that is also the lightest one and is characterized by the presence of one proton and one electron. Its valency is 1 and thus it usually links to adjoining elements via one sigma bond and can either shed or gain one electron to create ions. This property is very essential in organic chemistry because the molecule of hydrogen is a part of many molecular compounds such as water and hydrocarbons. Hydrogen’s valency is also one, which offers a rationale for its participation in acid-base reactions besides the formation of hydrogen bonds vital in many biological processes as well as in most materials.
