Presentation Transcript

  1. Ionic Bonding • Positives will be attracted to Negatives. • The force of the attraction between a Positively Charged Ion and a Negatively Charged Ion is called an IONIC BOND. • When two Ions Bond, they form an Ionic Compound. Ex 1. NaClEx. 2 CaS

  2. Ionic Compounds • PositiveIon is called a CATION. • Negative Ion is called an ANION. • Write down 2 other cationsand anions that you think would fit together

  3. Ionic Compounds • Notice the cross over of Charges • The Cation is always written FIRST, Anion Second. • Ionic compounds are made up of metals and non-metals, the metal is written FIRST.

  4. Formation of Ionic CompoundsCrossing Rule Ca+2+ Cl-1 CaCl2

  5. Ionic Structure • Ionic Compounds:Compounds made up of positive and negativeions that have resulted from the transfer of electrons from a metal to a non-metal.

  6. Naming Ionic Compounds • Regular names: • Write the name of the metal first • Replace the ending of the non-metal with –ide • eg. Mg3P2 → Magnesium Phosphide

  7. Naming Ionic Compounds • Transition Metals: • When a metal can form more than one type of ion • State the charge using a Roman numeral • eg. CuBr → Copper (I) Bromide • Eg. CuO → Copper (II) Oxide

  8. Naming Ionic Compounds • Acids: • Recognized by the H+ ion out front (but not like in water, H2O, that’s covalent) • Name it using the non-metal, but with the ending -ic • eg. HCl → Hydrochloric acid • Eg. HF → Hydrofluoric acid • Try HI → Hydroiodic acid
