Atomic Theory

Which of the following correctly describes the structure of an atom using the symbols 'p' for protons, 'n' for neutrons, and 'e' for electrons, and indicates the charges of each particle?

• Protons (p, +) and neutrons (n, 0) are in the nucleus, electrons (e, -) orbit around the nucleus.

• Protons (p, -) and electrons (e, +) are in the nucleus, neutrons (n, 0) orbit around the nucleus.

• Neutrons (n, +) and electrons (e, 0) are in the nucleus, protons (p, -) orbit around the nucleus.

• Electrons (e, 0) and protons (p, 0) are in the nucleus, neutrons (n, -) orbit around the nucleus.
