True, Protons, neutrons and electrons are subatomic particles., Protons and neutrons are also known as nucleons., Protons are inside the nucleus of an atom., Neutrons are inside the nucleus, Electrons move constantly outside the atom’s nucleus., Electrons have the smallest mass of the three subatomic particles., A proton carries a single positive electric charge., A neutron has no electrical charge; it is neutral., An electron carries a single negative electric charge., Atoms have no overall charge because the number of protons equals the number of electrons., If a particle has 3 protons and only 2 electrons, its net charge is +1., Almost all of an atom’s mass is concentrated inside its nucleus., Protons and electrons have equal‑size but opposite‑sign charges., When there are more protons than electrons in a particle, the particle carries a positive charge., False, Electrons are nucleons inside the nucleus., Neutrons have a small positive electrical charge., Protons move outside the nucleus like electrons., Electrons have the largest mass among subatomic particles., A normal neutral atom has more electrons than protons., Nucleons include protons, neutrons and electrons., If a species has 5 protons and 7 electrons, it has a positive charge., Protons are neutral particles with zero charge., Most of an atom’s total mass comes from electrons., Neutrons orbit around the outside of the atomic nucleus., An atom is neutral when neutrons and protons have equal numbers., If a particle has 4 protons and 2 electrons, its charge is −2., Electrons are heavy particles kept inside the nucleus., Subatomic particles are all larger than a full‑size atom., Positive charge appears when there are more electrons than protons.
