2 What do I know already about Chemistry?

3 Topic/Question 1 What does an atom look like? Include all subatomic particles

4 Topic/Question 1 Remember, the most current model is the electron cloud

5 Topic/Question 2 What are groups and periods on the periodic table?

6 Topic/Question 2 Groups are families (columns) of elements. These have elements share many important characteristics Periods are rows with elements that share the same number of energy levels.

7 Topic/Question 3 What is the importance of electrons?

8 Topic/Question 3 Electrons give the element is chemical properties. Valence electrons are the outermost electrons that do all of the bonding and help us to predict how an element will bond.

9 Topic/Question 4 What is the Octet Rule and how does it relate to chemical bonding?

10 Topic/Question 4 The octet rule states that atoms form chemical bonds through giving, taking and sharing electrons, to achieve a stable electron configuration like that of a noble gas (a full outer shell…. Usually 8 electrons)

11 Topic/Question 5 Write down everything you know about an ionic bond.

12 Topic/Question 5 Ionic bonds involve a metal and a nonmetal. Metals give or transfer electrons to a nonmetal. That exchange is what causes the bond to form. These are strong bonds and are typically solids with high melting points.

13 Topic/Question 6 Write down everything you know about a covalent bond?

14 Topic/Question 6 A Covalent Bond is formed between two nonmetals when electrons are shared to satisfy the octet rule.

15 Topic 7: Ionic Naming and Formula Writing In Chem B, if you are given a word equation, you will need to use chemical symbols to write the chemical formula. Can you give the chemical formula for magnesium bromide? And iron (III) phosphate

16 Topic 7: Ionic Naming and Formula Writing magnesium bromide Iron (III) phosphate

17 Topic 8: Creating Covalent Compounds What would the formula be for carbon tetrabromide? What would the formula be for diphosphorous pentaoxide? Remember:

18 Topic 8: Creating Covalent Compounds carbon tetrabromide? diphosphorous pentaoxide?
