If we take say methane, with FOUR C−H covalent bonds, we split this up to give 4×. H , and a carbon atom with 4 valence electrons. … A polyatomic ion is a charged chemical species with more than one type of atom present.

Is methane a polyatomic ion?

4.8: Polyatomic Molecules- Water, Ammonia, and Methane.

Is there ions in CH4?

To sum up, methane is a covalent compound with a molecular mass of 16 and the simplest of all alkanes. It is a flammable non-toxic gas. It is a tetrahedral molecule that has 4 equivalent C-H bonds. Since the electronegativity difference between carbon and hydrogen is very low, it is a covalent compound.

Well-known examples of such polyatomic ions are the sulfate ion (SO42–), the hydroxide ion (OH–), the hydronium ion (H3O+), and the ammonium ion (NH4+).
