Question: 1 / 400

What is the positively charged dense center of an atom called?

Nuclear fusion

Nuclear reactor

Nucleus

The positively charged dense center of an atom is called a nucleus. This is the correct answer because the nucleus is the core of an atom, where most of its mass and positive charge is concentrated. Option A, nuclear fusion, is the process of combining two atomic nuclei to form a heavier nucleus, so it is not the name of the center of an atom. Option B, nuclear reactor, is a facility where nuclear reactions take place, but it is not the name of the center of an atom. Option D, optic nerve, is a nerve that transmits visual information from the retina to the brain, and is not related to the structure of an atom.
