Stuff to deal with the periodic table and such..just shoot me a PM and we'll chat.
The assignment is basically about this "periodic table from another universe". Most of the patterns are still the same, Oxidation numbers, mass increase, radius increase, etc. etc. The shape is apparently NOTHING like ours, however.
Somethings just THREW me off.
Element W Q and K are in the same family. K is unreactive, which means they would all be "Noble Gases". Right? Well, W has an electron configuration of 1n4 and the element Triangle has a configuration of 2n4, meaning they would be in the same family, riiiiiight? Well, it also says triangle has many metalloid properties...? O_o
Also. U can lose 3 electrons or gain one to become stable, giving it oxidation numbers of +3 or -1. J also has a -1 oxidation number. Element R has the greatest electronegativity, making it like Flourine, the topmost element next to the Noble Gas family. HOWEVER. U has the lightest atomic weight in its family...
O________________o
I'm not sure if I'm just placing things wrong because there are many more conflicts. Some are very straightforward. For example, S has 21 protons, but I have no idea where that would be. I don't know if the metalloid staircase is...crossing through the stable elements which would make..the stable elements right in the middle of the periodic table...it's just all very confusing.

It is a Chicago Chem thread.
Aigoo - I cannot help you. If I had about 5 hours and your chem book, I might have an answer!

I assume this is not due tomorrow????
We had parent/teacher conferences tonight. Minor issues, but I am not happy with a few grades, my wife thought I scared the 22 year old teacher.

Posted: 11/21/05 at 11:29pmNo, no. It's due next Monday, but this is just one of those things I feel like I'l never figure out. I mean, I've read these element descriptions so many times!

Ok, Aigoo, I'm going to try and lend as much of my pathetic chem knowledge as possible...
If K is unreactive, it must be a Noble gas because, as I was taught, they are too "noble" to mingle with other elements outside of their group... therefore, they are preppy farts.
If the other elements are 1n4 and 2n4, does that refer to the electron energy level? Would four be the number of Valence electrons? If so, you could work backwards from that one formula that determines lvl.
If Triangle has many metalloid properies, wouldn't it have to be Radon, Xenon, or Krypton?
Other than that, you've lost me... in fact, I think I lost myself... sorry if I only confused you more... I know I did.

The 1 and 2 in the 1n4, 2n4 describe the energy level, meaning they'll be on seperate rows. The 4 indicates the same number of electrons on that "n" cloud, which means they'll be in the same family (column).
The thing with Triangle is that it has the same number of electrons on the same cloud as an unreactive element meaning that it would be a noble gas as well. However, it states that Triangle has many metalloid properties (and since the staircase thing doesn't touch the noble gases on our periodic table) which leads me to think
The entire "stable/noble gas" column is around where the metalloids are found and Triangle falls to where it can be the level 2 energy level as well as touching the staircase thingy, assuming it still exists.
But moving THAT throws off everything else.
