Make a web that includes the 3 types of bonds weve discussed
Ionic, Covalent, and Metallic
Slide 3
Bond between two nonmetals They SHARE electrons
Slide 4
Electronegativity! Electronegativity the tendency of an atom to
gain electrons in a chemical bond. If the difference between the
electronegativity's is large, the bond tends to be ionic. is small
it tends to be covalent Compounds can have both, but usually show
one type more than the other chemically, usually tend to be
ionic

1. Diatomic Molecules There are 7 diatomic molecules H 2, N 2,
O 2, F 2, Cl 2, Br 2, I 2 NEVER found as single atoms if alone
(Thats why they all have a 2 Naming: Their names are just the name
of the element
Slide 6
2. Binary Molecular Compounds Nonmetals without Hydrogens (H)
Formula DOES NOT start with an H Naming 1. First Element Use the
entire name of the element 2. Second Element Change the ending to
ide 3. USE NUMERIC PREFIXES Only time you wont use a prefix is if
there is only one atom of a particular element. DO NOT WORRY OR
EVEN THINK ABOUT CHARGES!!
Slide 7
Slide 8
CCl 4 As 2 O 3
Slide 9
Always begin with H + Two Types Binary Oxyacid *** Remember:
The number of hydrogen atoms in the acid equals the charge of the
anion
Slide 10
3. Binary Acids Have an H + but no O Naming 1. Use the prefix
hydro 2. Then take the root of the second acid 3. Add ic to the end
4. Follow with acid
4. Oxyacids Must have a polyatomic ion Naming 1. Identify the
polyatomic ion 2. Use the root of the anion 3. Depending on the
suffix (end) If it ends in ate change to ic If it ends in ite
change to ous
Slide 13
HNO 3 - 1. Identify the polyatomic ion Nitrate 2. Use the root
of the anion Nitr 3. Depending on the suffix (end) If it ends in
ate change to ic If it ends in ite change to ous Nitric Acid
Nitrate ends in ate So change to ic
Slide 14
Compound containing carbon and hydrogen Named using prefixes
that correspond to the number of carbons in the compound. 1 meth 2
eth 3 prop 4 but After this it used the normal prefixes
Slide 15
Ending refers to the type of functional group found in the
compound. -ane alkane - simplest hydrocarbon - only has single
bonded carbons with hydrogens -ene alkene - has a double bonded
carbon in the formula -yne alkyne - has a triple bonded carbon in
the formula
