which change to the model would improve its accuracy?\na. move each neutron so it is next to a proton.\nb. move the protons and neutrons to a small space in the center.\nc. move the protons and electrons to a small space in the center.\nd. move all of the particles so that they are evenly spaced.
Answer
Brief Explanations:
In an atom, protons and neutrons are located in the nucleus at the center. Electrons orbit around the nucleus. Moving protons and neutrons to a small space in the center (the nucleus) would make the model more accurate as this represents the real - life structure of an atom. Option A is incorrect as neutrons and protons are randomly arranged in the nucleus, not necessarily next to each other. Option C is incorrect because electrons do not reside in the nucleus with protons. Option D is incorrect as particles are not evenly spaced in an atom; protons and neutrons are in the nucleus and electrons are in orbitals around it.
Answer:
B. Move the protons and neutrons to a small space in the center.
