Detailed explanation-1: -The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms. This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons.
Detailed explanation-2: -Valence electrons are the electrons in the outermost shell, or energy level, of an atom.
Detailed explanation-3: -Valence Electrons The valence shell is the outermost shell of an atom in its uncombined state, which contains the electrons most likely to account for the nature of any reactions involving the atom and of the bonding interactions it has with other atoms.
Detailed explanation-4: -The outermost shell of any atom is called the valence shell and the electrons that reside in the valence shell are called valence electrons. When the valence electrons in any atom gain sufficient energy from some outside force, they can break away from the parent atom and become what are called a free electrons.
