In an electrically neutral atom,the number of protons in the nucleus is balanced by an equal number of
A)neutrons.
B)quarks.
C)orbital electrons.
D)all of these
E)none of these

Question

Quizplus · Accepted Answer

In an electrically neutral atom, the number of negatively charged electrons orbiting around the positively charged nucleus exactly balances the number of positively charged protons in the nucleus. Neutrons are electrically neutral and have no charge, so they do not contribute to the overall electrical neutrality of an atom. Quarks are subatomic particles that make up protons and neutrons and are not directly involved in the overall electrical charge of an atom. Therefore, the correct answer is C) orbital electrons.
