In an atomic model that includes a nucleus, negative charge is

Explanation:

Every atom consists of three sub-atomic particles which are protons, neutrons and electrons.

Protons have a positive charge, neutrons have no charge and electrons have a negative charge.

Inside the nucleus of an atom, there will be only protons and neutrons. Whereas electrons revolve around the nucleus of an atom.

Therefore, we can conclude that in an atomic model that includes a nucleus, negative charge is concentrated outside the nucleus of an atom.

if you mean hydrogen and oxygen then water is the product
