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.
yes it is polyatomic ion because it is made up of more than 2 atoms
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.
The polyatomic ion is a carbonate ion, with formula CO3-2.
This is the ion acetate.
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.
HCO3- is the polyatomic ion with which sodium bonds. It is the bicarbonate ion.
