O B. Since electrons are 1836 times less massive than either protons or neutrons, most of the mass of an atom is in the nucleus, which is only 1/100,000th the size of an entire atom… A small percentage of hydrogen atoms have 1 or even 2 neutrons. SCI.8.5a . An atom consists of a positively charged nucleus surrounded by one or more negatively charged particles called electrons. The number of protons found in the nucleus equals the number of electrons that surround it, giving the atom a neutral charge (neutrons have zero charge). The neutrons are inside the nucleus and have a neutral charge. What does a nucleus do in an atom? Electrons are negatively charged ; In a neutral atom (no surplass charge) the number of electrons orbiting the nucleus is equal to the number of protons inside the nucleus.
