"An atomic nucleus is positively charged because it is composed of neutrons."
No.  Neutrons have no charge.

"An atomic nucleus is positively charged because it is composed of protons."
Yes.  Each proton has a tiny positive charge.

"An atomic nucleus is negatively charged because it is composed of electrons."
No.  An atomic nucleus is positively charged.  Electrons do have negative charge on them, but there are no electrons in the nucleus.

"An atomic nucleus is negatively charged because it is composed of neutrons."
No.  An atomic nucleus is positively charged, and neutrons have no charge anyway.
