Identification of the number of valence electrons present in atoms of Li , Group 1A element. Concept Introduction: The electrons present in the outermost shell of the atom are known as valence electrons. Valence electrons are important because: The valence electrons decide the reactivity of an element. The valence electrons decide the way an atom forms a bond with another atom. The valence electron in an atom decides the combining capacity of the element. Except inner transition elements valence electrons are present in s or p subshells of elements. For inner transition elements incompletely filled d or f subshells electrons are considered as valence electrons.
