Which of the following largely determines an atom's atomic weight?
A) the number of neutrons
B) the number of electrons
C) the number of electrons in the outer shell
D) the number of protons and neutrons
Atomic Weight
The average mass of atoms of an element, calculated using the relative abundance of isotopes in a naturally-occurring element.
Neutrons
Subatomic particles found in the nucleus of an atom, with no electric charge and a mass slightly greater than that of protons.
Protons
Protons are positively charged subatomic particles found in the nucleus of an atom.

Final Answer :
D
Explanation :
The atomic weight of an atom is largely determined by the sum of the number of protons and neutrons in its nucleus, as these particles contribute the most to the atom's mass. Electrons have a much smaller mass and do not significantly affect the atomic weight.
