i found it kind of funny how he talked about his stars wars collection and how he flushed R2-D2 down the toilet. he talked a lot about polar and non polar and gave it a real life problem to them it was easier for me to understand that way.
1: I found the bonds such as non-polar covalent, paler covalent and Ionic were very interesting. 2: the analogy of Star wars helped me understand how molecules liked to have eight all the time
1. Atoms combine by sharing electrons. The octet rule shows images of atoms and molecules and their valence electrons with color code. It shows how the valence electrons combine to make other substances. For example: Oxygen has 6 Valence Electrons (VE) and Carbon has 4 VE's. If you combine two oxygen atoms and one carbon atom, Each Oxygen atom can share 2 VE's with the carbon, 4+2+2=8, and the Carbon atom can share 2 VE's with both of the Oxygen atoms, 6+2=8. 8 is a complete set. 2. The key for Bonds: 0
Non-Polar Covalent
.5
Polar Covalent
1.7
Ionic
Combine the Electronegativity (EN) of each atom to get your number. For example. Hydrogen has an EN of 3.44, and Oxygen has an EN of 2.20. 3.44 - 2.20 = 1.24: Polar Covalent ADC
its non polar and the video is very educational and i think that we should do that in class go through some different things and finding out what they are. J.C.W.
The man explained everything very well, To be specific he talked about how to find a compound's type of bond which is to subtract the second kind of atom from another one. If the difference was between 0 and 0.5 it was a non-polar bond. If it was between 0.5 and 1.7 then it was a polar bond, and if it's greater than 1.7 then it's an ionic bond. The way he related how compounds combine with the star wars action figures helped me to understand that atoms always want 8 electrons on the outside level. M.J.S.
In a covalent bond, atoms are sharing electrons. Tn an ionic bond, electrons are being transferred between two atoms. The octet rule is a complete set of electrons. Electronegativity is a measure of how much atoms want electrons. The more it wants, the higher its electronegativity is. The guy did a good job with using the star wars toys as an analogy. LGS
I found the way that he used star wars in this helpful because I know that I kind of like star war so it engaged me in what he had to say. it was interesting that there was a name for all of these bonds between chemicals. I found the part about its activity pretty cool and how you could find out how much electronegativity the element had because of the amount of electrons in the last row
Just a side note it is pretty funny how he flushed R2-D2 down the toilet
I think I got it but how you know the atoms number was not well explained. since we all ready talked about how they are attracted it didn't really help with the star wars comparison, Although it was creative. I really like chemistry and want to find a brand new element. G.J.G.
There are 3 different types of chemical bonds. Polar, non-polar, and ionic. It was funny how he related collecting Star Wars action figures to the octet rule. I would have never thought to compare the two. It's true though. It was a very creative way to explain it, and I think that now I will always think of Star Wars when I'm thinking about the octet rule! JMJ

DeleteThe Star Wars hahaha. It did actually help a bit. He explained fairly well about the covalent bond and ionic bond.

ReplyDeleteI like how he explains the octet rule with the star wars and how they need 8 action fingers to have a complete set.CML

ReplyDeleteCorrection, there are 3 different kinds of bonds, but they are ionic, covalent, and metallic. JMJ
