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.
An ion is a charged particle. A polyatomic ion is a group of covalently bonded atoms that, as a whole, have a 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.
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.
To find the oxidation number or charge of a polyatomic ion, consider the known charges of the individual atoms within the ion. For example, in the sulfate ion (SO4)2-, oxygen typically has an oxidation number of -2, and sulfur would then have an oxidation number to balance the charge of the ion. The sum of the oxidation numbers of all the atoms in the ion should equal the overall charge of the ion.
