  1. Ionic V.S. CovalentANDCovalent V.S. Polar Covalent

  2. Ionic VS Covalent IONIC BONDS • Metal + Non-Metal • High in polarity • High in melting point • No definite shape • Strong electrolytes • ATOMS have to CHANGE to positive or negative before they bond • Valence electrons to hold atoms together (BOTH BONDS) • Forms molecules (BOTH BONDS) • Transfer of electrons (Large poles)

  3. Ionic VS Covalent IONIC BOND

  4. Ionic VS Covalent COVALENT BONDS • All non-metals(Gases, Liquids, Solids) • Low in polarity • Low in melting point • Definite shape • Uses prefixes • Atoms do not need to change in order to bond • Non- Electrolytes • Valence electrons to hold atoms together(BOTH BONDS) • Form molecules(BOTH BONDS) • Sharing of electrons

  5. Ionic VS Covalent COVALENT BOND

  6. Ionic VS Covalent WHAT DO BOTH BONDS HAVE IN COMMON ? • Valence electrons to hold atoms together • Form molecules

  7. Non Polar VS Polar BUT…There are two types of covalent bonds NON- POLAR COVALENT V.S. POLAR COVALENT

  8. Non- Polar VS Polar Electronegativity • IF POLAR- The difference in the electronegativity will be greater than 0.5 but less than 2.0 • IF NON-POLAR- The difference in the electronegativity will be less than 0.4

  9. Ionic VS Covalent PRACTICE ! • What kind of bond is Sodium Bromide • What kind of bond is NH3 • What kind of bond is Acetylene • What kind of bond is Hydrogen Dioxide • What kind of bond is MGO

  10. Ionic VS Covalent Check your answers ! • Sodium Bromide – Ionic • NH3- Polar Covalent • Acetylene- Non Polar Covalent • Hydrogen Dioxide- Polar Covalent • MGO- Ionic
