2. Sodium trioxocarbonate(IV).
   (Valency: Na=1, CO₃ =2)


3. Potassium carbonate 
(Valency: K=1, CO₃ =2)


4. Magnesium carbonate 
(Valency: Mg=1, CO₃=2)


5. Zinc carbonate 
(Valency: Zn=2, CO₃=2)


6. Copper(I) carbonate 
(Valency: Cu=1, CO₃ =2)


7. Iron(II) carbonate 
(Valency: Fe=2, CO₃=2)


8. Lead(II) carbonate
 (Valency: Pb=2, CO₃=2)


9. Barium carbonate
 (Valency: Ba=2, CO₃ =2)


10. Lithium carbonate
 (Valency: Li=1, CO₃=2)


11. Ammonium carbonate (Valency: (NH₄=1, CO₃=2)

                     Assignment

                              Atom An atom is the smallest particle of an element which can take part in a chemical reaction.                 Components of an atom An atom has two main parts: I. The nucleus (made of proton and neutron) II. The shells (electrons) which surrounds the nucleus at definite distance.                   Structure of an atom                    Sub-particles of an atom An atom is made up of three sub-particles namely: I. Proton II. Electron III. Neutron  Proton and neutron are the nuclear particles found in the nucleus, while the electrons are in constant and continuous motion in the shells at various energy levels around the nucleus.         Characteristics of the sub-particles  ...

                Relative Atomic Mass The Relative Atomic Mass (RAM) of an element is the average mass of its atoms compared with one-twelfth (¹/₁₂) of the mass of one atom of carbon-12. The carbon-12 isotope (¹²C) is used as the standard for measuring atomic masses. Relative atomic mass of an element  = average mass of one atom of element     ¹/₁₂ × the mass one carbon -12 atom                     Relative Moleculer Mass Relative Molecular Mass ( RMM ), also called Molecular Weight, is the sum of the relative atomic masses (RAM) of all the atoms present in a molecule. The RMM has no unit (it’s a ratio). It shows how heavy a molecule is compared to ¹/₁₂  of the mass of one atom of carbon-12 (¹²C). Examples: 1. Water (H=1, O=16)  H₂O = (2 × H) + (1 × O)          = (2 × 1) + (16)        ...
