I assume you mean 1+ .
NH4 +
Ammonium. ( the 1 is implied )
Ammonim-NH4 There's also Hydronium - H3O
A polyatomic ion. For example, ammonium, chemical formula (NH4) with a 1+ electrical overall charge.
The charge on the polytomic ion cyanide is -1.
A polyatomic ion is held together by covalent bonds between atoms. They can be either positive or negative. For example, the ammonium ion, NH4+, has a positive charge, and the sulfate ion, SO42-, has a negative charge.
No, oxide is just an oxygen ion. The formula is just O(-2 charge), hence not a polyatomic ion. Hydoxide on the other hand is a polyatomic ion, formula being OH(-1 charge)
No, Methane (CH4) is not a polyatomic ion. It doesn't have a charge, therefore it can't be an ion. It's considered a hydrocarbon.
The only polyatomic ion with a positive oxidation number is the ammonium ion, which has the formula ( \text{NH}_4^+ ). In this ion, nitrogen has an oxidation state of -3, while each hydrogen has an oxidation state of +1, resulting in a total charge of +1. As such, ammonium is unique among polyatomic ions for having a positive charge.
No. S2- is a monatomic ion. A polyatomic ion contains at least two atoms. You can identify a polyatomic ion as it will have the symbols for more than one element (OH-), a subscripted number (O22-), or a combination of the two (CO32-). The superscript in the ion only indicates the charge.
An ion is a charged particle. A polyatomic ion is a group of covalently bonded atoms that, as a whole, have a charge.
Yes. its two elements bonded with a charge left over... that's the definition of a polyatomic ion Is a common one? idk
SO4-2The sulfate ion is a polyatomic ion made up of one sulfur atom and four oxygen atoms, that exists only if it can gain 2 electrons (from some metal cation or cations). It has a charge of -2. Note that this is the sulfate ion and not the sulfiteion.
The algebraic sum of the oxidation numbers of all atoms in a polyatomic ion is equal to the overall charge of the ion.
