Question 174

Which statement about the structure and charge of a neutral atom is correct?

A

The nucleus contains neutrons and electrons, while protons orbit the nucleus.

B

An atom is electrically neutral because the number of positive protons in the nucleus equals the number of negative electrons orbiting the nucleus.

C

Protons and neutrons are located in the nucleus and share equal but opposite electric charges.

D

An atom is electrically neutral because neutrons carry a negative charge that cancels the positive charge of protons.
