No. There is a hydronium H3O+ ion, but it can only exist in an aqueous solution. There are also organic analogues to the ammonium ion in which one of the hydrogen atoms in an ammonium ion is replaced with a hydrocarbon group. There is also the Mercury I ion, Hg22+.

Is ammonium soluble?
AmmoniA is soluble in water. Ammonium is a polyatomic ion and can only exist as the positive HALF of a compound, not independently.
Which of these is an example of a polyatomic cation?
The ammonium ion, NH4+, is the only polyatomic cation.
Which ionic compound contains only non metalic elements?
it must be a compound of a polyatomic cation (i think ammonium might be the only one) and any polyatomic anion that contains no metals (sulfate, chlorate, carbonate, etc). Some examples would be (NH4)2SO4, (NH4)2CO3, etc.
What are quaternary ammonium compounds?
Quaternary ammonium compounds are partly ionic compounds that contain in each molecule one nitrogen atom covalently bonded to four distinct carbon atoms. This bonding is only possible as part of a polyatomic cation with a single positive charge, and the complete compound therefore requires an anion to achieve electrical neutrality.
What is the only polyatomic ion with a 1 plus charge?
Ammonim-NH4 There's also Hydronium - H3O
Are polyatomic ions positively charged?
Most polyatomic ions have a negative charge. There are only 2 positive polyatomic ions; Mercury(I) ion and Ammonium ion. False.

Which of these is an example of a polyatomic cation?
The ammonium ion, NH4+, is the only polyatomic cation.
The only known polyatomic ion with a 1 charge?
I assume you mean 1+ . NH4 + Ammonium. ( the 1 is implied )
Which is an example of cation ammonium hydroxide chloride or fluoride?
The only cation (positively charged ion) is ammonium NH4+ the others are all anions (negatively charged ions)

What are the similarities of polyatomic ions and monatomic ions?
Anions and cations are ions of a single atom of a single element (i.e. Lithium+1, Fluorine-1, etc.). Polyatomic ions are charged particles composed of multiple atoms of different elements (i.e. Nitrate (NO3)-1, Ammonium (NH4)+1, etc.).
Why are compounds with polyatomic ions considered to be both ionic and covalent?
It is possible for a compound to possess both ionic and covalent bonding. a. If one of the ions is polyatomic then there will be covalent bonding within it. b. When a polyatomic ion combines with another ion, then there is an ionic bond
What are ions are polyatomic?
A charged ion that is composed of two or more atoms covalently bonded.No: Each chloride ion contains only one atom.
What happens when you mix two polyatomic compounds in one formula?
What happens when you mix two polyatomic Compounds?For example:1. Ammonium + Carbonate = (NH4)2(CO3)This is corrector2. Ammonium + Carbonate = NH4 2CO3This is not correctThe general rule is that we would only put brackets around a poly atomic if we have more than one of them in our compound.So (NH4)2CO3 would be how it should've been shown as.Although the first example is still correct and usable as an answer.
