Question:
Anything that influences the valence electrons will affect the chemistry of the element. Which one of the following factors does not affect the valence shell?
(a) Valence principal quantum number (n)
(b) Nuclear charge (Z)
(c) Nuclear mass
(d) Number of core electrons.

Answer:

Valence electrons are the electrons which are present in the outermost shell or valence shell of an atom and are responsible for the reactivity of any compound. Option (c) Nuclear mass does not affect the valence electrons because the nuclear mass is so small, it is considered as negligible.
