Label the element square.
What is an oxidation number?
How do you think we can use these numbers to predict the type of bond formed? (ionic, covalent)
Atomic # 10 Ne
Neon
20.180
Chemical Symbol
Element Name
Avg. Atomic mass #
The charge of an atom when it gains, loses, or shares an e- in a chemical bond.
Elements close to noble gasses tend to give or take e- and form ionic bonds.

3. Title: Naming Compounds
L.O. SWBAT use the periodic table to predict compound names.

5. Ionic bonds
On the periodic table, strong electron donors are on the left side (alkali metals).
Strong electron acceptors are on the right side (halogens).
The further apart two elements are on the periodic table, the more likely they are to form an ionic compound.

6. covalent bonds Form when electrons have equal tendency to accept e-.
Elements are both nonmetals and tend to be close together on the periodic table.

12. Summary – Binary vs Poly
Naming Compound Rules Page
Binary Compounds
Write the name of the 1st element
Mg = Magnesium
Write the root name of the 2nd element
Br = Bromine = brom-
Add the suffix –ide to the root name
brom + ide = bromide
Write the name
MgBr2
lower case
Magnesium bromide

Prefix: Specify the #
N2 = di + nitrogen
Write the root name of the 2nd element
Suffix: - ide
O4 = tetra + ox + ide
Write the name
N2O4
Dinitrogen tetraoxide
