A valence shell is:

A. an atom's outermost electron shell.
B. where an atom's neutrons are located.
C. what determines an atom's atomic number.
D. an atom's outermost proton shell.

Valence shell is the outermost shell of an atom that contains valence electrons, which are the electrons involved in forming chemical bonds. The number of valence electrons determines an atom's reactivity and bonding behavior. For example, in a carbon atom with an electron configuration of 1s²2s²2p², the 2nd principal shell holds the 4 valence electrons.
