*inorganic polyatomic –ate ion which does not have 3 or 4 oxygen atoms: Cyanate  CNO1-

 

Plot the –ate oxyanion formula into the nonmetal section of the periodic chart:

Do you see a relationship between the oxyanions with three oxygens atoms in the formula to those with four oxygen atoms with the position on the periodic table?
