(NH4)2O
Ammonium is NH4+ Oxygen is O-2 When you use the criss cross method you switch the charges and put the NH4 in bracketssicne it is a polyatomic ion and it has set ratios.
Added:I'm very sorry to inform you that ammonium oxide does NOT exist!Even the ammonium hydroxide, much better known as ammonia, doesn't exist.
Citation in wikipedia:
Ammonium hydroxide, also known as ammonia water, ammonical liquor, ammonia liquor, aqua ammonia, or aqueous ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH3(aq). Although its name suggests a salt with composition [NH4+][OH−], it is not actually possible to isolate samples of NH4OH - it exists only in dilute aqueous solutions.
NH4+ is not an alkali metal, though it forms halogenides, nitrates and other salts like K+ and Na+.
In a 1M ammonia solution, about 0.42% of the ammonia is converted to ammonium, NH4+, equivalent to a pH of 11.63.
NH3 + H2O NH4+ + OH−.
The base ionization constant is
Kb = [NH4+][OH-]/[NH3] = 1.8×10−5

Is ammonia and ammonium hydro oxide are same?
No: The formula of ammonia is NH3 and the formula of ammonium hydroxide is NH4OH. The latter is formed spontaneously when ammonia dissolves in water.
What is NH42O?
Ammonium oxide
How can you separate ammonium chloride and copper oxide?
Ammonium chloride is soluble in water and copper oxide not; dissolve the mixture and filter.
What is the formula of ammonium sulphite?
The formula for ammonium sulfite is (NH4)2SO3.
Ammonium sulfide formula?
The formula for ammonium sulfide is (NH4)2S.
what is the chemical name for (NH4)2O?
This formula is for ammonium oxide.
What is the ionic formula for ammonium oxide?
There is a compound ammonium hydoxide, NH4OH (cannot be isolated - only in solution) there is no ammonium oxide, if there wrer it would have the forula (NH4)2O
What is NH4 and K2O?
NH4 is the chemical formula of the ammonium ion.K2O is the chemical formula of the potassium oxide.
Is ammonia and ammonium hydro oxide are same?
No: The formula of ammonia is NH3 and the formula of ammonium hydroxide is NH4OH. The latter is formed spontaneously when ammonia dissolves in water.
Is ammonium oxide covalent or ionic?
If ammonium oxide existed it would be ionic. However, because the oxide ion is such a strong base this compound would immediately turn into ammonium hydroxide and water.
What is NH42O?
Ammonium oxide
How can you separate ammonium chloride and copper oxide?
Ammonium chloride is soluble in water and copper oxide not; dissolve the mixture and filter.
What is the chemical formula for NH4 and NO3?
NH4NO3 - ammonium nitrate. (since the valencies of both radical are 1).
What is the formula of ammonium sulphite?
The formula for ammonium sulfite is (NH4)2SO3.
Ammonium sulfide formula?
The formula for ammonium sulfide is (NH4)2S.
Ammonium fluoride formula?
The chemical formula of ammonium fluoride is NH4F.
Formula for the polyatomic ion ammonium?
The chemical formula of ammonium is (NH4)+.
