Do anyone here happen

[1024]

to know a lot about or have a major in chemistry?

[Derfud]

I did very well in the 10th grade portion, but that probably isnt what you are looking for. But all in all, chemistry pwns.

[EarlyDawn]

I'm decent at it.

Why are noble gases unreactive?

[Infernus]

let me see what i can remember... the noble gases are unreactive because they have nothing to share with anythign else... and no gaps to fill... atleast thats what it is if i recall correctly...

[1024]

sweet. thanks.

all right, heres another:

what does the term polar mean, when it comes to covalent bonds?

i hate finals...

because they already have an octet, meaning that their outer-most energy level is full.

:/ i knew it was soemthign abotu them not being able to recieve anymore electrons...

A Polar covalent bond is the weakest of all bonds, but it is a very special bond. The best example is water. Water is H20, and when the Hydrogen's bond, they become slightly positive. The oxygen end of the molecule is slightly negative. This causes the slightly positive Hydrogen end to become attracted to a slightly negative Oxygen end of another water molecule. This is why water "sticks" to each other.

Their outer electron layer is full. Atoms react to either fill it or give it to another atom to fill...if it's full already, it won't share.

My god what are they teaching you these days... God did! Either that or it was magic.

... All I know is that they have their valence electrons in more than one shell. I haven't taken chemistry yet so I can't really tell you much more.

Oh god, all this is on the tip of my mind, but I can't quite reach it. I remember doing all this stuff though, hated it.
