Basic Formation of Compounds

 
5.1  Basic Formation of Compound
 
Stability of Noble Gas
  • Noble gases are the elements in group 18.
  • These gases are stable is because they have a stable duplet or octet electron arrangement at the valence shell.
  • Duplet electron arrangement is referring to Helium, and octet electron arrangement is referring to other elements in group 18.
  • The electron arrangements of these elements make the elements chemically non-reactive as it is very stable.
 
Chemical Bonds
Formed when electron transfer or electron sharing takes place.
 
The image shows a diagram explaining the types of chemical bonds. At the top, there is a label that says ‘Types of Bonds.’ Below this, there is a cartoon illustration of a person. Two arrows point from the person to two boxes. The box on the left is labeled ‘Ionic bond (donate or receive electron),’ and the box on the right is labeled ‘Covalent bond (share electron(s)).’ The logo ‘Pandai’ is in the top left corner.
 
Condition for the Formation of Chemical Bonds
  • Noble gas does not form any bond, as it has a very stable electron arrangement.
  • The formation of a bond can happen between elements in group 1 to group 17.
  • Group 1 has only one valence electron, whereas group 17 only has seven valence electrons.
  • These elements do not have a stable duplet or octet electron arrangement.
  • Therefore, these elements are reactive and able to form a bond.
  • There are two types of bonds.
    • Ionic bond (donate or receive electron)
    • Covalent bond (share electron(s))
  • The process of the formation of ionic bond and covalent bond, only involve valence electron(s).
