Answer:
protons=electrons=9(atomic number)
Neutrons=19-9=10(math number-atomic number)
You may find the electron diagram of ammonia and the ammonium ion in the attached picture.
Explanation:
Ammonia NH₃ have covalent bonds with the hydrogen atoms in which for each bond one electron comes from nitrogen atom (blue dot) and the other from the hydrogen atom (red dot). You may see that the nitrogen remains with the lone pair of electrons that does not participate in bonding.
Ammonia NH₃ have a basic character and is able to accept a proton H⁺ from an acid to form the ammonium ion NH₄⁺. The fourth bond formed its called a coordinative-covalent bond that is created only with the nitrogen lone pair of electrons (blue dots).

Co2 will dissolve in water if water is saturated with Co2 first then it will absorb some of CO2 it appear as less is absorb that was actually the case . this would make it appear as present of CACO3 is in original sample is lower than it will be too low
