Valence electrons:
- For main group elements (i.e s-block and p-block elements), the valence electrons are the electrons present in the outermost orbit.
- But for most of the transition and inner transition elements, the valence electrons are the electrons present in the shells outside the noble gas core.
If you want a Periodic table with Valence electrons, then visit Periodic table with Valence electrons labeled in it. (Where you will get the HD images along with the explanation).
