Explanation / Answer

A polyatomic ion (monoatomic ion) is a charged species which has two or more atoms held together by covalent bonds. Polyatomic ions are used in the preface of acid and/base chemistry and considered as conjugate acid/base of a neutral molecule.

For example, The Polyatomic ion of MgCl2 is Cl2-. and Mg2+

The Polyatomic ions(s) for each compound i) Na2SO3 is SO32-

    ii) KNO3 is NO3-

   iii) Cs2CO3 is CO32-

   iv) NH4OH is OH-

    v) K2HPO4 is HPO42-

   vi) NaHCO3 is HCO3-

  vii) Ba(NO3)2 is NO3-
