Valence electron is define as number of electron in outermost shell however valency is define as the capability of atom to gain or lose electron to complete outermost shell.for explaple atomic mass of oxygen is 16 so the number of electron in shell is 2,8,6. thus valence number of electron is 6 however...

Valency is the number of electrons loose or gain by atom to complete its outermost shell and valence electrons is number of electrons in outermost shell of an atom. For example atomic number of nitrogen is 7 and electronic configuration is 2,5 so here number of valence electrons is 5 and valency is 3...

In chemistry, a valence electron is an electron that is associated with an atom, and that can participate in the formation of a chemical bond; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair. The presence of valence electrons can determine...

In chemistry, a valence electron is an electron that is associated with an atom, and that can participate in the formation of a chemical bond; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair. The presence of valence electrons can determine the element's chemical properties and whether it may bond with other elements: For a main group element, a valence electron can only be in the outermost electron shell. In a transition metal, a valence electron can also be in an inner shell. read less

Valence electrons are the number of electrons in the outermost energy level of an atom. Valency is the number of electrons an atom needs to gain or lose in order to have a full outermost energy level.

mathematics learning is easy and interesting if fundamentals are clear.

Valency is the ability of an atom to lose or gain electrons while valence electrons is the number of electrons in its outermost shell.
