Elements are identified by their atoms' number of protons. So different neutron amounts will not affect the identity of the atom.

For example, a Hydrogen atom has only 1 proton and no neutrons (H¹). If you add a neutron and make it 1 proton and 1 neutron (H²), it will still be a Hydrogen but just a different isotope which is called Deuterium.

Thus, the answer is D

The statement which is completely accurate is atoms of the same element can have the different number of neutrons.

What is atom?

Atom is the smallest unit of the matter consist the positive charged nucleus and the electrons which moves around it. The atom can not be divided further.

The atom of a matter, made by three elements-

  • Neutron, is the element of atom, which has zero charge.
  • Proton, is the element of atom, which has positive charge.
  • Electron, is the element of atom, which has negative charge.

Let's check which statement is correct-

  • A. Atoms of the same element always have different numbers of neutron-Atoms of the same element may or may not have different numbers of neutron. This is not the correct option.
  • B. Atoms of the same element always have different atomic weights-Atoms of the same element may or may not have different atomic weights. This is not the correct option.
  • C. Atoms of the same element can have neutrons but exist without a proton-All atom has proton and neutron in nuclei (except hydrogen). This is not completely accurate.
  • D. Atoms of the same element can have the different number of neutrons-atoms of the same element can have the different number of neutrons, known as isotopes. This option is correct statement.

Hence, the statement which is completely accurate is atoms of the same element can have the different number of neutrons.
