A hydrogen atom and a chlorine atom do not exist in the nature. They exist as hydrogen molecules, H2 and chlorine molecules, Cl2 because they are more stable as molecules rather than as atoms. Think about these and explain the reason.
When hydrogen gas and chlorine gas react one of another, as a result, hydrogen chloride, HCl is formed. Now what do you think about this process? Is it because the elements of H2 and Cl2 are less stable than HCl? If your answer is yes, so give me the reason. Remember, do not only say yes, OK? Always give the reason by using a strong argumentation. Write a paragraph to make a good explanation.
Don't forget to explain about duplet and octet systems; discuss the tendency of atoms in order to achieve their stability as same as the noble gas that the position is closely to these atoms, in the periodic table. Compare the Lewis structure of H2, Cl2, and HCl. Classify the type of covalent bonding, which is(are) a non polar covalent bond and which is (are) a polar one.
After you conclude the above concept, develop your knowledge by thinking about polar molecules and non polar molecules, the different polarity of molecules.
