Respuesta :

Answer: The correct statement is the nucleus is very tiny but has most of the mass.

Explanation:

There are three sub-atomic particles in an atom:

  • Protons: They are positively charged species present in the nucleus of an atom.
  • Electrons: They are positively charged species present around the nucleus of an atom.
  • Neutrons: They are neutral species present in the nucleus of an atom.

Nucleus is defined as the positively charged center of the atom consisting of protons and neutrons. All the mass of atom is contained in the nucleus.

From Rutherford's Gold foil experiment, the nucleus of an atom occupies a very little place.

Hence, the correct statement is the nucleus is very tiny but has most of the mass.
