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.
Polyatomic number are ions made up of more than one atomic element
polyatomic ions are those ions which carry more than one atom,we can say that a group of atoms having single charge( which may be positive or negative) are polyatomic ions.
A polyatomic Radical is a atom that differs from other because it has come into contact with a massive energy force and fused it into a different form
Oxygen
120o. The polyatomic ion is planar with a trigonal molecular geometry, a nitrogen atom with 3 equidistant O atoms at near 122 pm. All predictable ny VSEPR. The short bond length is attributed to pi bonding, the negative charge is spread across the three O atoms.
The polyatomic ion is the ammonium ion, NH4^+
A polyatomic ion.
The polyatomic ion SO5 does not exist. The closest polyatomic ion to this is SO4^2- which is called sulfate ion.
The polyatomic ion for nitrite is NO2-.
The polyatomic ion is a carbonate ion, with formula CO3-2.
No, "co3" is not a recognized polyatomic ion. However, "CO₃²⁻" is the carbonate polyatomic ion.
KOH is an ionic compound with a polyatomic ion. The hydroxide ion (OH-) is a polyatomic ion that is composed of one oxygen atom and one hydrogen atom.
This is the ion acetate.
The polyatomic ion is a carbonate ion, with formula CO3-2.
Na2Cr2O7 is an ionic compound with a polyatomic ion. The polyatomic ion present in this compound is the chromate ion (Cr2O7)^2-.
Polyatomic ion in the compound Na2O2 is known as peroxide. Such polyatomic ion contains two or more atoms covalently bonded.
Li is the symbol for Lithium it is an element not a polyatomic ion
