Which best describes the nucleus of an atom?
mamaluj [8]

Answer:

The answer is D.

I used the process of elimination to find your answer if you want to understand further look in my explanation. I hope I can help! Have a great day!

Explanation:

So the negatively charged part of a atom is the electron cloud so A is wrong because it would be in the wrong spot. Plus the nucleus is positively charged because it contaims only protons ans neutrons. Neutrons are neutral and protons are positive so the protons over power the nuetrons. Therefore the nucleus is not made of neutrons and electrons so C is wrong. And B is also wromg because the nucleus does indeed have mass. So the correct answer is D, it is the most massibe part of a atom.
