Chemical Name Vs. Formula

Chemical Name: A Scientific name given to a compound *tells us what it elements it is made up of

Examples: Sodium sulfide, Carbon dioxide

*Sometimes we use trivial (meaningless names): Water, Methane

Chemical Formula: Scientific symbols given to a compound from the periodic table

Examples: H2O, CO2 , NaS

• Is gold a metal or nonmetal?• Is sulfur a metal or nonmetal?• Is calcium a metal or nonmetal?

Question


12

November 19, 2014

Metals and Non- Metals in compounds

You can have a mixture of metal and non metal elements in your compounds:

• 3 major groups:1. Metallic compounds

2. Covalent compounds

3. Ionic compounds

Metal and metal

Non- metal and non-metal

Metal and non-metal


13

November 19, 2014

Ionic Vs. Covalent

Covalent bond: A nonmetal and nonmetal compound bond between elements = Sharing electrons Create Molecular compounds (Molecules)

Examples: Water (H2O), Carbon dioxide (CO2)

Ionic Bond: A metal and a nonmetal compound bond between elements = Give or Take electrons Create Ionic compounds

Examples: Sodium chloride (NaCl), Calcium Carbonate (CaCO3)

Vs!

Ratio of elements

• A compound can have more than 1 of each element in it

H2O Has 2 Hydrogen and 1 Oxygen atoms, 3 atoms in all

CO2 Has 1 Carbon and 2 Oxygen atoms, 3 in all

CaCO3 Has 1 Calcium, 1 Carbon and 3 Oxygen, 5 in all

* be careful: *elements can have two letters

Co CobaltCO Carbon and Oxygen

* The prefix only belongs to the element in front of it

CO2 2 oxygen not 2 Carbon

Naming Ionic Compounds

Ionic compound Rules:

1. Ionic compounds are made of a metal and non metal

2. The metal's name goes first

3. Only the first name gets capitalized

4. The last name always ends in ide

Examples: NaCl : Sodium chloride

CaCl2 : Calcium chloride


18

November 19, 2014

Name the following Ionic compounds:

1. MgO :

2. K3N:

3. BeF2:

4. Li2S:


19

November 19, 2014

Naming Covalent/Molecular Compounds

Covalent compound Rules:

1. Covalent compounds are made of 2 nonmetals

2. Only the first name gets capitalized

3. The last name always ends in ide

4. If there is more than 1 atom of an element we give prefixes

Examples: SiO : Silicon oxide

CO2 : Carbon dioxide


20

November 19, 2014

Prefixes

• Prefixes are given to Covalent/Molecular compounds:

2 atoms : di

CO2 : Carbon dioxide

3 atoms : tri

F3P : Triflourine phosphide

4 atoms : tetra

BCl4 : Boron tetrachloride

* No prefix given for just 1 atom


21

November 19, 2014

Name the following Covalent compounds:

1. SCl2:

2. NO4:

3. PCl2:

4. SO3:


22

November 19, 2014

Conclusions?

• Element Vs. Compound?

• Name Vs. Formula?

• Metals Vs. Nonmetals?

• Ionic Vs. Covalent?


23

November 19, 2014

Answer the following questions based on the item below:

NO31. Element or compound?

2. Molecular or covalent?

3. How many atoms all together?

4. What is it's full name?
