Molecule Webpage

SOOOO im done with my molecule webpage or have been done.

AND IT LOOKS AWESOME (;

lalalala Mr.Olson is coming around to check it now.

i want to go home!! im so bored -o- and tired...and hungry. i can't wait till brunch and lunch.

Polar Bears and Penguins

We read a comic called "The Bare Essentials of Polarity" and it was about polar bear and penguins. It was teaching us about polarity and bonding between atoms in greater detail. It also taught us the concept of electronegativity, which helps us to understand partial charges.

polar molecule is just a molecule with a difference in electrical charge between two ends.

electronegativity tends to rise as you move "northeast" on the periodic table, and decrease as you move "southwest". Electronegativity is the ability of an atom/nucleus to attract bonding electrons toward itself.

Attractice Molecules

This lab was pretty cool.

We used 4 molecules in this lab.

water,
acetic acid,
isopropanol,
and kerosene

We poured one liquid at a time into the buret. We had a charged wand, and when we put the wand next to the liquid coming out of the buret, the liquid might bends/ attracts to the wand.

The molecules that were attracted was water, acetic acid, and isopropanol. Kerosene was not attracts.

recently

we learned about the Lew Dot Structures.

Gilbert Newton Lewis
1875-1946

Discoverer of the covalent bond,
inventor of the Lewis Dot Structures,
and the theory of Lewis Acids and Bases

the greatest chemist to ever not win a noble prize

-Covalent Bond-shared pair of electrons
-Always put the element that forms the most bonds at the center of the structure

we did a lab called Let's Built It.
