Which statement correctly describes the nucleus of an atom a. most volume of an atom is taken up by the nucleus b. the charge on the nucleus determines the charge of the atom c. most of the mass of the atomis located in the nucleus

The answer should be C, most of the mass of the atom is located in the nucleus.

First, we need to know that an atom includes mainly 3 subatomic particles, which are proton, neutron, and electron. Proton and neutron are located in the nucleus of the atom, while electrons are moving freely outside the nucleus. Each proton carries a positive charge, neutron has no charge, and each electron carries a negative charge.

A is not correct because the nucleus only takes a small space from the atom, instead, the area for the electrons takes up the most space.

B is not correct because only proton locates in the nucleus, and the charge of the atom is also determined by the number of electrons outside of the atom.

And c is correct because protons and neutrons are the heaviest, while electrons are so light that sometimes we can neglect their weight.

Therefore, your answer should be C.
