Adams combined to form a nucleus, the neutrons C molecules, D electrons

Answer 1

It seems like there may be some confusion in your question. Neutrons, electrons, and molecules are different components of an atom.

Atoms are made up of a nucleus, which contains protons and neutrons, and electrons that orbit around the nucleus in different energy levels. Protons carry a positive charge, electrons carry a negative charge, and neutrons have no charge.

Molecules, on the other hand, are formed when atoms combine through chemical bonds. A molecule is a group of two or more atoms held together by chemical bonds.

So, in summary, atoms combine to form molecules, and within an atom, neutrons, protons, and electrons are the subatomic particles that make up its structure.
