Question

Quizplus · Accepted Answer

Electrons have a negative charge and are significantly less massive than protons, which are positively charged particles found in the nucleus of an atom. Neutrons are neutral and also located in the nucleus but do not have a charge. Molecules are made up of two or more atoms bonded together and do not pertain to the question of charge and mass in the context of subatomic particles. The nucleus consists of protons and neutrons and is overall positively charged due to the protons.
