<span>it will convert the energy produced by a chemical reaction into usable electric power.</span>
The correct answer is 3.
In any atom, the nucleus will be positively charged because the only ions in the nucleus are neutrons, which have a neutral charge, and protons, which have a positive charge.
Electrons are negatively charged, and they are in the orbital, thus making the orbital negatively charged.
<span>C, Neutrons are inside the nucleus of an atom. Rutherford was able to theorize that if neutrons were in the center, and electrons were orbiting in separate energy levels, then protons must be in the nucleus to keep the neutrons bound and not free floating, and if the nucleus has neutral and positive particles, then it has to be a positive nucleus.</span>
