Se valence electrons




Valence electrons, their variation in the periodic table and relation to reactivity and electrical conductivity of elements.

Tin is located in group 1color(red)(4) of the periodic table, which means that it has color(red)(4) electrons in its outermost shell, i.e. color(red)(4) valence electrons. Valence electrons are the total number of electrons present in the outermost shell of an atom (i.e. in outermost orbital). The valence electron for a neutral atom is always definite, it cannot be varied (more or less) in any condition for a particular atom and may or may not be equal to its valency.
