Intro
• What is a chemical bond?
    Well, its simple a chemical bond is an attraction between
  electrons of one atom to the nucleus of another atom
 tHeRe ArE 3 TyPeS Of cHeMiCaL BoUnD:
 Ionic
 Covalent
 Polar covalent

Most atoms form chemical bond in order to be stable and have
  8 electrons in their valence orbital. Which means they will
  share,give,or take electrons from other atoms
Ionic bounding




Formation:
  the transfer of electrons between atoms , which will cause both atoms with a cation
    (postive) and anion(negtive).
 3 physical properties:
Melting point
Boiling point
Non-conductors in dry state
The energy involved in the formation of an ionic bond is from the positive (cation) and
    negative (anion)
Ionic pics
Covalent bonds
• How does the octet rule apply to atoms?
   electrons are shared between each other
Formation of covalent bounds :
 Single: 2 electrons are shared between atoms
 Double: 4 electrons are shared between atoms
 Triple: 6 electrons are shared between atoms
Covalent bonds
Covalent Bonds 2
Sigma Vs. Pi Bonds
  sigma =end-to-end=single
   pi=side-to-side= unhybridized=double

How is bond length related to bond dissociation energy?
 As bond length decreases bond dissociation energy decreases
Metallic Bonds
• What is a metallic bond?
  chemical bond that holds the atoms of metal together

How conductivity of electricity and high melting point are by
  metallic?
  When they bond, positive nuclei is formed with a “sea” of
  floating electrons moving in between the nuclei . This causes
  a great bond between them.
Metallic bond 2
• What is alloys ?
  metal made by the combining of 2 or more metallic
  elements, to give greater strength or resistance to corrosion.
