Which part of the atom has a negative charge? The electron cloud has a negative charge. Which particle (if any) is neutral? The neutron is neutral. Which part of the atom has a positive charge? The nucleus has a positive charge due to protons. Which nuclear emission has the greatest mass? Alpha particles have the greatest mass among nuclear emissions. Which nuclear emission has the greatest mass? Alpha particles have the greatest mass among nuclear emissions. What part of an atom has a negative charge? The electron cloud has a negative charge. Which part of an atom has a positive charge? The nucleus has a positive charge due to protons. Which particles have a negative charge? Electrons have a negative charge. Which particle does not affect the charge? Neutrons do not affect the charge. What is one way neutrons are different from electrons? Neutrons are neutral and found in the nucleus; electrons are negatively charged and orbit the nucleus. Which particles are not affected by the strong force? Electrons are not affected by the strong nuclear force. Neutrons have which type of electrical charge? Neutrons have no electrical charge. Which of the following subatomic particles has appreciable mass and lacks a charge? The neutron has appreciable mass and lacks a charge. Which subatomic particle is most movable in an atom and can occupy an orbital? Electrons are the most movable and occupy orbitals. Which particle has a negative charge? The electron has a negative charge. Which symbol represents a particle that has a mass approximately equal to the mass of a neutron? n⁰ represents a neutron, which has a mass about equal to a proton. What is the charge of a proton? A proton has a positive charge (+1). How are electrons different from protons and neutrons? Electrons are much lighter and have a negative charge; protons and neutrons are heavier and found in the nucleus. Which particle is J. J. Thomson credited with discovering: electron, neutron, proton, or photon? J.J. Thomson is credited with discovering the electron. What subatomic particle acts like a mini-magnet? The electron acts like a mini-magnet due to its spin and charge. Which statement describes the location of two types of subatomic particles in a helium atom?
