Which statement correctly describes the nucleus of the atom?

Question

The nucleus of the atom contains the electrons.
The nucleus of the atom is mostly empty space.
The nucleus of the atom surrounds the center of the atom.
The nucleus of the atom contains most of the mass of an atom.

Answer 1

The statement that correctly describes the nucleus of the atom is: "The nucleus of the atom contains most of the mass of an atom."

The nucleus is composed of protons and neutrons, which collectively account for the majority of an atom's mass. Electrons are found outside the nucleus in what is referred to as the electron cloud, and the atom itself is mostly empty space. The other statements are incorrect in this context.
