Because an ion has an electric charge.
because they're not
I predict that an ion of sodium will have a charge of plus one.
A metal replaces a metallic ion below it on the list.
No a molecule is a molecule, polar or nonpolar.
Neither. Magnesium sulphate is ionic; individually the sulphate ion is polar.
Think of the sulfite ion as a molecule with its geometry and dipole moment AND a net charge. The electron pair geometry is tetrahedral and the molecular geometry is trigonal pyramidal and because of its asymmetrical shape and polar bonds, sulfite has a net dipole moment (2.04D ). The ion is polar.
it is an alkali metal so it forms Cs+ ion.
I predict that an ion of sodium will have a charge of plus one.
Ammonium ion is polar due to the ionic bonds present in the polyatomic ion.
Having recently needing to answer this question on an online homework, the answer is simpler than expected. The question is really just asking for the "symbol" of fluorine which is F- Another example would be if it asked, "Predict the ion formed by Na (sodium)." The answer would simply be Na+
It can help identify whether or not the molecule or ion is polar as well as identify if there are any "ends" of the molecule which can be more easily involved in a reaction.

no nonpola in all ion .
N
No a molecule is a molecule, polar or nonpolar.
No a molecule is a molecule, polar or nonpolar.
The ion bromate is of course polar.
