WAEC Chemistry
Which of the following species determines the chemical properties of an atom?
a.
Electron
b.
Neutron
c.
Nucleus
d.
Proton
Correct answer: A
The chemical properties of an atom are determined by the electrons in the atom. Only electrons take part in chemical reactions. Neither the protons nor the neutrons in the nucleus of atoms are involved in chemical reactions so they do not determine the chemical properties of atoms.
