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


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)


Ionic VS Covalent

IONIC BOND


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


Ionic VS Covalent

COVALENT BOND


Ionic VS Covalent

WHAT DO BOTH BONDS HAVE IN COMMON ?

  • Valence electrons to hold atoms together

  • Form molecules


Non Polar VS Polar

BUT…There are two types of covalent bonds

NON- POLAR COVALENT

V.S.

POLAR COVALENT


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


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


Ionic VS Covalent

Check your answers !

  • Sodium Bromide – Ionic

  • NH3- Polar Covalent

  • Acetylene- Non Polar Covalent

  • Hydrogen Dioxide- Polar Covalent

  • MGO- Ionic
