The formula of an ionic compound will contain at least one metal and one non-metal element. Metals are the elements one the left side of the periodic table of elements and non-metals are located on the right side.

If it has a Group I or II metal then it is an ionic compound.
Group III and the Transition metals also give ionic compounds, but the further you go towards Group 0 the more covalent compounds become.
Examples of ionic compounds:-
Sodium hydroxide (Na(I)OH)
Calcium Chloride (Ca(II)Cl2)
Copper Sulphate (Cu(II)SO4)
Aluminium Nitrate (Al(III)(NO3)3)
The Roman Numeral in Brackets (II) indicates its valent power - its oxidation number.

I would say it is ionic if it is the compound of a metal with a nonmetal or a compound of a metal with a polyatomic anion made up on nonmetals.
I would say it is ionic if it is a compound of an element in groups IA, IIA, IB-VIIIB with an element in the "northeast" section of groups IIIA-VIIA.
