Question

an atom consists of
select one:
o a. one nucleus and only one electron
o b. one nucleus and one or more electrons
o c. protons, electrons, and neutrons
o d. answers (b) and (c)

Explanation:

An atom has a nucleus (which contains protons and neutrons) and one or more electrons. Option b is correct as there is one nucleus and electrons (the number can vary). Option c is also correct as protons, electrons, and neutrons are the main sub - atomic particles in an atom (except for hydrogen - 1 which has no neutrons, but generally, atoms have these three). So, since both b and c are correct, the answer is d.

Answer:

D. answers (b) and (c)
