Chamisal Bonding Regents Review

Chemical bonding

What are the three types of Chemical Bonding?

​A metal TRANSFERS electrons to a non-metal

Ionic Bonds

Two or more non-metals SHARE electrons

Covalent Bonds

Atoms of the same element float around in a sea of electrons

Metallic Bonds

Writing Ionic Compound Formulas

​Rules for Naming Ionic Compounds

• Name the metal (no change)

• Name the non metal next

• Change the end of the name to "IDE"

  Oxide, chloride, bromide, iodide, etc.

• When naming ionic compounds with transition metals you need to include roman numerals to show the charge of the metal..

Criss Cross the charges

Criss Cross the charges

Criss Cross the charges

​Rules for writing Ionic Compound formulas

• Ionic bonds have metal and non-metal.

• Find the Metal on the periodic table and note the charge

• Find the non metal on the periodic table and note the charge.

• Criss Cross the charges

• If the charges are the same they cancel each other (do not write the numbers)

Polyatomic Ions

Table E

• Polyatomic Ions are usually found on the non-metal side of the compound

• Ammonium and Hydronium are the only positive polyatomic ions on the table

​Rules for writing Compound formulas with Polyatomic ions

• Find the polyatomic ion on table E and note the charge. Find the metal on the periodic table

• Cris cross the charges only

• Do NOT change the numbers in the ion, only focus on the charge. You must write all the numbers in the ion when writing formulas

• Use parentheses ( ) to separate the number in polyatomic ion and the charge coming down from the Metal ion

Cris Cross only the charges

​Rules for Naming Compounds with Polyatomic ions

• FName the metal first, no change

• Check if there are more than 1 non meta;, if so go to table E

• Find the name of the polyatomic ion on Table E

• Copy the name next to the name of the metal
