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. We can write the configuration of oxygen’s valence electrons as 2s²2p⁴.
Detailed explanation-2: -Valence electrons are the electrons that are found in the outermost energy level of an atom.
Detailed explanation-3: -The outermost energy level that (in the ground state of the atom) contains electrons is called the “valence shell” of the atom. These valence electrons are responsible for all chemical bonds between atoms.
Detailed explanation-4: -The valence electrons for the representative (main) group of elements are found in the outermost (highest energy) s and p sublevels. They are often together called the valence shell.
Detailed explanation-5: -Valence electrons are the electrons that are found in the outermost energy level of an atom. The amount of them will determine both the properties and the reactivity of that atom. The easiest method for determining amount of valence electrons in an atom is by referencing the group number.
