USING THE LAPTOPS1) THERE IS NO FOOD OR DRINKS NEAR THE LAPTOPS2) Laptops are not for personal use!3) You must ONLY work on the laptop assigned to you.4) You are to ONLY go on the sites assigned by the
teacher5) Keep the computer away from the tables edge6) Treat the laptop with care -> they are brand new!
DO NOT write, scratch, or peel the material labels off the laptop!!
Anyone unable to follow the rules will no longer be allowed laptop use for the rest of the semester, marked as cutting, and will be given an automatic detention.
Inquiry: What are some pros and cons of nuclear energy?

Each box on the periodic table represents a profile of a different element or type of atom. Letter symbols are used to represent the name of each atom.
- Symbols always begin with a Capital Letter.
(i.e. H = Hydrogen)- If symbol has more than one letter, the
rest of the letters are in lower case. (i.e. He = Helium)

L.O.: SWBAT EXPLAIN THE PURPOSE OF THE PERIODIC TABLE IS AND TO READ A CHEMICAL FORMULA.
Describe the make up of each molecular formula1) O2 (oxygen) 2) CO2 (carbon dioxide)
3) C6H12O6 (sugar)
4) HCl (Hydrochloric Acid)
5) H2SO4 (Sulfuric Acid)
6) Which of the above molecules is NOT a compound? Why?
2 oxygen’s. 2 atoms in total
1 carbon and 2 oxygen’s. 3 atoms in total
6 carbon’s, 12 hydrogen’s and 6 oxygen’s. 24 atoms in total
1 hydrogen and 1 chlorine. 2 atoms in total
2 hydrogen’s, 1 sulfur, and 4 oxygen’s. 7 atoms in total
O2 is not a compound because it only has 1 element.

Chemical Bond: Fusion: 2 atoms connecting the nuclei of 2
atomsby the e- to form a molecule joining to form a new
elementHYDROGEN
HYDROGEN
Chemical reaction: When new molecules are
formed.
Vs. Nuclear reaction: when a different
element is formed.
Inquiry: Is fusion technology good or bad?
