This molecule (ammonia) is neutral.
Nitrogen can covalently bond to three other atoms where as hydrogen can covalently bond to one other atom. Therefore, nitrogen can covalently bond with three hydrogen atoms to form ammonia. As all electrons are charge balanced by the protons, the molecule is neutral.
Ammonia dos react with water, although not 100%, when it dissolves
NH3 +H2O -> NH4+ + OH-
The production of OH- in this reaction means that ammonia is a base.
Ammonia (pure liquid ammonia) undergoes auto- ionisation
2NH3 <-> NH4+ + NH2-
NH2- is the amide ion, which carries a -1 charge.
The electrical charge on any compound not named as an "ion" is always zero.
Zero
Ammonium hydroxide is an ionic compound. However, both ions in the compound have covalent bonds inside them. Solid ammonium hydroxide does not exist, it is only found in solution and is formed when NH3 is dissolved. NH3(aq) + H2O <-> NH4+ +OH-
Molecular Eq HC2H3O2(aq) + NH3(aq) -> NH4+(aq) + C2H3O2-(aq) Ionic Eq H+(aq) + C2H3O2-(aq) + NH3(aq) -> NH4+(aq) + C2H3O2-(aq) Net Ionic Eq H+(aq) + NH3(aq) -> NH4+(aq)
i think NH3 Is just the co-valent bond. It is formed by bonding between three hydrogen atom which are slightly positively charged and a single atom of nitrogen which is negatively charge .
NH3 is not a cation - it is polar but uncharged. however, when NH3 is dissolved in water, it forms NH4+ and OH-, and NH4 is a cation.
No, NH3 contains only covalent bonds.

(in short) No, whilst in their solid state ionic crystals are very poor conductors of electricity, however when molten or dissolved their ions are able to carry charge, therefore they are very good conductors of electricity when molten or dissolved in e.g. water. Pure water is a very poor electrical conductor too, it's the dissolved ions that carry the charge.
polar covalent
it has a positive (+) charge
which of the following substances is least likely to be ionic : a) nh3 b) caf2 c) na2o )mg br2
Yes, you are right.
Covalent because they share electrons
