Review of this week

Oxidation Notes

Bonding Worksheet

Bonding and Lewis Dot diagrams

We reviewed Oxidation numbers and then proceeded to practice drawing Lewis Dot Diagrams of two elements combining.
Students should know the difference between ionic and covalent bonds.
We will have a quiz tomorrow on the next 15 elements and the two different types of bonds.
Homework: Study

Oxidation Numbers

Students were introduced to oxidation numbers. Students should realize that these numbers correspond to the number of electrons an atom will either gain or lose to make an outer shell of 8. Losing an electron(s) fives a positive number and gaining electron(s) will result in a negative oxidation state.

Electron Movement

Can you make a piece of plastic bag float? That was the question the students had to answer today using the tools that I provided them.
Students also received a list of the next 15 elements that they need to know for an upcoming quiz.

Element Tiles

Students continued with presenting their element tiles and then taped them together according to groups so that we can hang them all up in the hallway for a Giant Periodic Table
There is no homework.
