Question

question 9 of 10
which of an atoms electrons are involved in chemical reactions?
a. the electrons closest to the nucleus of the atom
b. the electrons that determine the atomic number of the atom
c. the electrons that make one isotope different from another
d. the electrons farthest from the nucleus of the atom

Explanation:

Chemical reactions involve the transfer or sharing of electrons. Valence electrons, which are the electrons in the outermost shell (farthest from the nucleus), are involved in bonding and chemical reactions. Electrons closest to the nucleus (core electrons) are not involved. The atomic number is determined by protons (not electrons). Isotopes differ in neutron number (not electron number).

Answer:

D. The electrons farthest from the nucleus of the atom
