Detailed explanation-1: -Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.
Detailed explanation-2: -Electrons present in the outermost orbit (valence shell) are called valence electrons.
Detailed explanation-3: -Valence electrons occupy the outermost shell or highest energy level of an atom while core electrons are those occupying the innermost shell or lowest energy levels. This difference greatly influences the role of the two types of electrons in a chemical reaction.
Detailed explanation-4: -The electrons present in the outermost shell of an atom are known as charged electrons/ valence electrons.
Detailed explanation-5: -Valence electrons are found in the orbitals associated with an atom’s highest occupied energy level. The remaining electrons, which are called inner shell electrons, do not participate in bonding and are, therefore, not important to study.
