In this section we look at how atoms combine to form chemicals and the effects of those bonds?
What are the properties of compounds that have covalent bonds? ionic bonds? metallic bonds?
How does the type of bond influence the structure of the compound?
We also want to be finding interesting experiments in chemistry. Why are they important and how do they tie in with what we are covering? To help get the ball rolling we can look back at some great discoveries and experiments throughout history in the Science Channel's presentation of 100 Greatest Discoveries: Chemistry.
This weeks contract compares types of bonds, models molecules, and investigates buckminsterfullerene.

does a fullerene have a neutral charge? and if they cant form in nature how do we form them?
buckminsterfullerene molecules are in the shape of a soccer ball.
they do form in nature and can be found occasionally in soot.
Do quarks or smaller particles have anything to do with the way atoms and molecules of different compounds organize?
Yes, leptons will influence the structure because electrons are in that category.
Buckminsterfullerene was the first fullerene to be discovered.
i posted mine but im not sure if i posted
after all of us knowing, that salt is ionic and can let electricity go through to light a lightbulb, do you guys think it is possible to create much bigger electricity by sticking a humungous copper wire into the ocean with a battery attached to it to make much greater electricity?
because the ocean is just like the salt water in the cup that made the lightbulb glow.
I was going crazy trying to figure out what bond silver bromide has and then I looked at the name.... Ohh!!! BromIDE!! It's bromide because when it's an IONIC compound you change the ion that has a negative charge to have an ide at the end of it's name... OHHHH I GET IT!!!!!
Austin,
Actually its more of a truncated icosahedron... don't ask
pania,
but maybe it would kill a few fish
Is buckminsterfullerene the only fullerene in the world, or are there many more?
Hey Hoopman, do you have any potassium permanganate in your stockhold?
Delaney, polar-covalent compounds end in -IDE sometimes, so make sure
Delaney,
there's nanotubes, nano-"onions", nanobuds, ball and chains, and a lot of types of buckyballs like c540 and different shapes to buckyballs like some have only hexagons, some have hexagons and pentagons, and some have heptagons mixed in there with them.
Anonymous quarks person,
look up particle physics. there's a table for different kinds of particles smaller than hadrons. it's kind of like a periodic table for really really small stuff.
Also, the term fullerene refers to any molecule composed completely of carbon in the shape of a hollow object, like an ellipsoid, ball or tube, so there are probably things we don't call fullerenes that actually fit into that category.
lets say oxygen is leaving after the reaction can you leave that out of the right side?
why would a log weigh less in weight after it burns
Nick,
because burning is a combustion reation, meaning that it gets rid of carbon dioxide, water, and combines them with oxygen and those things float away as smoke. so smoke is the sign of part of the log floating away, so there is less "log" and less mass.
Ian,
You have to indicate that oxygen comes off of it. lets say that somone doesnt know what comes off from their reation. they try it and hydrogen is emitted. but coincidentally, he is in the sahara desert, so all the hydrogen ignites and he dies. any questions?
