Study Online and Download KIPS 9th Class Chemistry Notes Unit 4: Structure of Molecules. The things around us are composed of matter. All matter is made up of the building units 'atoms'. These atoms combine to form molecules, which appear in different states of matter around us. The forces responsible for binding the atoms together in a molecule are called chemical forces or chemical bonds. These bonding forces which keep the atom together will be discussed in this chapter.

Students will be able to:
  • Find the number of valence electrons in an atom using the Periodic Table.
  • Describe the importance of noble gas electronic configurations.
  • State the octet and duplet rule.
  • Explain how elements attain stability.
  • Describe the ways in which bonds may be formed.
  • State the importance of electronic configurations in formation of ion.
  • Describe formation of cations from an atom of a metallic element.
  • Describe formation of anion from a non-metallic element.
  • Describe characteristic of ionic bond.
  • Recognize a compound as having ionic bonds.
  • Identify characteristics of ionic compounds.
  • Describe formation of covalent bond between two non-metallic elements.
  • Describe with examples single, double and triple covalent bonds.
  • Draw electron cross and dot structure of simple covalent molecules containing single, double and triple covalent bonds.
