C Correct answer
Explanation

Chemical properties of elements are primarily determined by valence electrons - the electrons in the outermost shell. These electrons participate in bonding and chemical reactions. Inner electrons and the nucleus don't directly participate in chemical bonding. Protons determine nuclear charge and atomic number, not chemical behavior.
