explain the relation between valency and valance electron
Answers
Answer:
Valency means combining capicity of an element . Relationship between the number of valence electrons and valency: Valence electrons are the number of electrons present in the outermost shell of an atom. Valency is the combing capicity of an element to form bonds with the other elements.
Answer:
The number of electrons present in the outermost orbit of an atom, or the number of electrons required to achieve stable configuration is the valency of an atom.
In an atom, the electrons are arranged in orbits with an increase in the energy levels around the nucleus. Thus, the valency or valence electrons in the outermost orbit of an atom are responsible for the emission spectrum and the chemical properties of the atom. Valency of an atom helps to decide if the atom will donate, accept or share electrons during a chemical reaction.
