Hydrogen is diatomic.
NH3 is its own compound.The elements in NH3 are nitrogen and hydrogen.
200. The formula is for every 1 Oxygen atom, 2 Hydrogen atoms must be present in water. Otherwise you would produce H2O2 (you cannot make it HO because it is never found in molecules on it's own) which is bleach.
On its own (as an ion), yes, it is -1. It is highly electronegative
Hydrogen is in its own chemical family as a nonmetal element on the periodic table.
Neither, it is an ion that cannot exist on its own as a substance. It is known as the fulminate ion. It combines with positive ions to form various compounds.
Hydrogen is just H, it is never found on its own as just H but rather H2.
Water is a compound. Hydrogen and oxygen agreements and the chloride ion, being an ion, is not a substance in its own right.
Ammonia is a compound with the formula NH3, it is a weak base. Ammonium is a polyatomic ion with the formula NH4+. The ammonium ion is formed when ammonia reacts with an acid and is itself mildly acidic. because it is positively charged is is not found on its own but accompanied by a negative ion such as in ammonium nitrate, NH4NO3.
A compound because elements are the basic forms of matter which, in this case, would be Hydrogen and Oxygen. Hydroxide is a mixture of the two.
Neither. No substance on its own on is an ion. Nitric acid is electrically neutral. When dissolved in water, nitric acid breaks apart, releasing both positive hydronium ions and negative nitrate ions.
Hydroxide is OH- it is a negative ion consisting of a hydrogen atom and an oxygen atom covalently bound together. The hydrogen ion is H+ indicating a single hydrogen atom with a positive charge. However, it rarely exists on its own. In an aqueous solution it bonds with a water molecule to form the hydronium ion, H3O+
That is a very interesting question. Hydrogen ions are usually represented as H+, but in fact this never exists on its own in chemical systems because it is too small and polarising. For instance, hydrochloric acid is usually represented as H+ and Cl-, but in fact the hydrogen ions are carried by water molecules, forming something like H3O+. However occasionally hydrogen forms the hydride ion, H-, in such compounds as Na+H-. Of course, all charges should be superscripts.

No, it is never to be found in the nucleus, it is in electron orbits or 'shells', each with its own the energy level.

Yes, Mg can exist as an ion. In its commonly found form, Mg2+, it has lost two electrons to attain a stable electron configuration. Mg2+ is a common ion found in various compounds and is important for many biological processes.
