If you mean H3O + then it is more commonly called the hydronium ion.
The molecule of nitric acid lose a hydrogen atom, not only a proton.
A proton is smaller than a nucleus, which is smaller than an atom, which is again smaller than a molecule.
It means transfer of proton (or H+ ion) from one molecule to another.
NADPH
In a molecule this is the cation.In the atomic nucleus this is the proton.
No. Proton acceptors.
The molecule of nitric acid lose a hydrogen atom, not only a proton.
Hydrogen only has one proton ,so it can pass that one proton onto another element, making it part of a molecule. It can become an ion if it loses that proton, or gains that proton.
No. A proton is a subatomic particle, and a component of atoms. Atoms are components of molecules. An organic molecule must contain carbon atoms.
A proton is smaller than a nucleus, which is smaller than an atom, which is again smaller than a molecule.
Smallest to Largest.. - Electron - Proton - Atom - Compound - Molecule
It takes a little bit of practice before it becomes natural to you, but acids are usually (not always) proton/hydrogen donors and bases are usually (not always) proton/hydrogen acceptors. I'm not sure how much you know about organic chemistry, but when a hydrogen is attached to a molecule that would be more stable without it (I'm using the words proton and hydrogen interchangeably), the hydrogen atom won't mind leaving the molecule - making it an acid. An example of this would be hydrochloric acid (HCl). When Cl- is alone, it is happy, because it has a full octet of electrons. It doesn't need the proton attached to it. If a hydrogen is attached to a molecule that would probably like another hydrogen, such as sodium hydroxide (NaOH), this molecule would be called a proton acceptor - a base. When Na+ OH- gets its proton (H+), it becomes H2O and Na+, a much more stable conformation of elements. There are a lot of factors that go into it though; there are no easy rules for telling the difference between acids and bases just by looking at their formula. Some other factors that go into it: hybridization, resonance stabilization, and electronegativity.
Proton
It means transfer of proton (or H+ ion) from one molecule to another.
water
The atomic mass of a molecule is equal to the number of protons plus the number of neutrons.
In a molecule this is the cation.In the atomic nucleus this is the proton.
