The nucleus occupies very little of the atom’s volume and contains little of its mass.
The nucleus occupies very little of the atom’s volume but contains most of its mass.
The nucleus occupies most of the atom’s volume and contains most of its mass.
The nucleus occupies most of the atom’s volume but contains little of its mass.
The nucleus is small and is the densest part of the atom.
The nucleus contains less than half the mass of the atom.
The nucleus contains small positive and negative particles.
The nucleus is large and occupies most of the atom’s space.
The force of the protons repelling each other is small compared to the attraction of the neutrons to each other.
The electrostatic forces acting between other atoms lowers the force of repulsion of the protons.
The interactions between neutrons and electrons neutralize the repulsive forces between the protons.
The forces holding the nucleus together are much stronger than the repulsion between the protons.
Electrons in neighboring atoms neutralize repulsive forces between protons
Neutrons effectively block the protons and keep them far apart to prevent repulsion
Electrostatic forces between neutrons and protons hold the nucleus together
Nuclear forces overcome repulsive forces between protons in the nucleus
