Which statement correctly describes the nucleus of the atom? a: the nucleus of the atom contains the electrons. b: the nucleus of the atom is mostly empty space. c: the nucleus of the atom surrounds the center of the atom. d: the nucleus of the atom contains most of the mass of an atom.

The correct answer is option D.

Explanation:

An atom is smallest unit of a matter or substance.It consist of three subatomic particles : electrons, protons, neutrons.

Protons are nucleus are located in the center of an atom where while mass of an atom is concentrated.

Atomic mass = Number of protons + Number of neutrons

Electrons are located outside the nucleus where they orbit in different energy levels around the nucleus.

Hence, from the given options the correct option describing the nucleus of an atom is option D.
