Ions

• An ________ is an atom or group of combined atoms that has a charge.

• A compound that is composed of ions is called an ____________________.

• Ionic compounds are usually start with a ________ or ________

• In ionic compounds, you will ________ valence electrons

Ions

• A ________, or positive ion, is formed when an atom ________ one or more electrons.

• An ________, or negative ion, is formed when an atom ________ one or more electrons.

• A ________ ion is one element with a charge

• A ________ ion is more that one element with a charge

Formation of Ionic Compounds

• Remember that objects with opposite charges ________ .

• The strong attractive force between ions of opposite charge is called an ____________.

• Don’t forget that even though the ions have charges, the overall charge of the compound will be …

• ________

Examples of Formula Writing

• Write the formula for the compound formed between sodium and chloride

Page 7: Naming - Ionic Compounds. Charges or Oxidation Numbers Group 1A ________ Group 2A ________ Group 3A ________ Group 4A ________ Group 5A ________

More examples

• Write the formula between Mg and Br

Page 8: Naming - Ionic Compounds. Charges or Oxidation Numbers Group 1A ________ Group 2A ________ Group 3A ________ Group 4A ________ Group 5A ________

More examples

• Write the formula for the compound formed between Ca and S

Polyatomic Ions

• Polyatomic ions are groups of covalently bonded atoms that have a charge

• For example:

• SO4 -2

• NO3 –1

• ClO3 –1

• NH4 +1

Page 10: Naming - Ionic Compounds. Charges or Oxidation Numbers Group 1A ________ Group 2A ________ Group 3A ________ Group 4A ________ Group 5A ________

Polyatomic Ions

• Writing formulas with polyatomic ions is the same.

• You just have to keep the polyatomic ions grouped together

• When you bring a number down to a polyatomic ion you MUST use parentheses!

Formula writing with polyatomic Ions

• Write the formula for the compound formed between sodium and nitrate

Page 12: Naming - Ionic Compounds. Charges or Oxidation Numbers Group 1A ________ Group 2A ________ Group 3A ________ Group 4A ________ Group 5A ________

• Write the formula between ammonium and sulfate

Formula writing with polyatomic Ions

Page 13: Naming - Ionic Compounds. Charges or Oxidation Numbers Group 1A ________ Group 2A ________ Group 3A ________ Group 4A ________ Group 5A ________

More examples

• Copper (II) and chlorine

• Silver and Nitrate

• Magnesium and sulfite

• Calcium and sulfur

• Potassium and oxygen

• Ammonium and phosphate

• Ammonium and chlorine

Don’t Forget!

• You have to remember the elements that form multiple charges (the ones with the roman numerals)

• That roman numeral will tell you the ________!

• For example: Copper (II) Cu +2

Page 15: Naming - Ionic Compounds. Charges or Oxidation Numbers Group 1A ________ Group 2A ________ Group 3A ________ Group 4A ________ Group 5A ________

• In naming ionic compounds, name the ________ first, then the ________.

• Monatomic ________ use the element name.

• Monatomic ________ use the root of the element name plus the suffix -ide.

• (This means 1 element with a negative charge will end in –ide).

Oxyanions

• Certain polyatomic ions, called ________, contain oxygen and another element.

• If two different oxyanions can be formed by an element, the suffix -ate is used for the oxyanion containing more oxygen atoms, and the suffix -ite for the oxyanion containing fewer oxygens.

Page 17: Naming - Ionic Compounds. Charges or Oxidation Numbers Group 1A ________ Group 2A ________ Group 3A ________ Group 4A ________ Group 5A ________

For example

• SO4 -2

• SO3 -2

• PO4 -3

• PO3 -3

• NO3 -1

• NO2 -1

Page 18: Naming - Ionic Compounds. Charges or Oxidation Numbers Group 1A ________ Group 2A ________ Group 3A ________ Group 4A ________ Group 5A ________

• Four oxyanions can be formed by the halogens

• In this case:

• Most – Per (root) – ate

• 1 less – (root) – ate

• 1 less – root – ite

• 1 less – hypo (root) - ite
