Answer :
The two atoms represented above contain the same number of:
1. Protons: Protons are positively charged particles found in the nucleus of an atom. The number of protons in an atom determines its atomic number, which is unique to each element. In the models given, if they represent different atoms, they would have a different number of protons.
2. Electrons: Electrons are negatively charged particles that orbit the nucleus of an atom. In a neutral atom, the number of electrons is equal to the number of protons to balance the charges. So, if the models represent different atoms, they would have a different number of electrons.
3. Neutrons: Neutrons are neutral particles found in the nucleus of an atom along with protons. They help stabilize the nucleus. The number of neutrons can vary within atoms of the same element, forming isotopes, which are atoms of the same element with different numbers of neutrons.
Therefore, based on the models given representing different atoms, the correct completion for the sentence would be that the two atoms contain the same number of neutrons.
