Finishing Up Ionic Bonds and Project Time Objective:

SWBAT find formula and name ionic bonds Catalyst:

What is an ionic bond? What is the oxidation number of Bromine? What is the formula for the ionic compound

formed between Magnesium and Fluorine?

You don’t know about transition metals! So.. the problem must tell you the

number of electrons. Cobalt (II) means that Cobalt gives

up 2 electrons

For POLYATOMICS it gets a bit more complexPb4+SO4

Naming Ionic Compounds

1)Write name of first element (metal).

2)Second element ends in -ide.

3)Ignore subscripts!

this…you will need it the rest of your life (in my class).

Naming Ionic Compounds

The way you use it…

Naming Ionic Compounds1) Look up the ions

on the cheat sheet and write the words next to

them.
