Question

vshiroky · Answer

It's 4 right @iPwnBunnies

vshiroky · Answer

Some of them I just need to double check.... others I may need actual help on haha

ipwnbunnies · Answer

Yes, because the quantum number L goes from 0 to (n-1).

ipwnbunnies · Answer

And L determines the subshells, dangit I can't remember what it's actually called.

ipwnbunnies · Answer

Angular momentum quantum number, yeah.

Which of the following atoms has the least metallic character?
A.Na 	
B.Cs 	
C.Li 	
D.Rb 	
E.K

vshiroky · Answer

That is Cs?

ipwnbunnies · Answer

Metallic character increase down the groups, and decreases across the periods (b/c nonmetals are on the right side.)

ipwnbunnies · Answer

So basically, whichever element is in the more top-right of the periodic table would be the LEAST metallic.

vshiroky · Answer

So Li?

ipwnbunnies · Answer

...No, Lithium is pretty metallic...because it's a metal. Cmon dude. Don't you have a periodic table?

vshiroky · Answer

I thought I was correct with Cs.. I'm looking at the table

vshiroky · Answer

Was I wrong with Cs?

ipwnbunnies · Answer

Idk, I don't have a periodic table with me right now.

Oh man, I'm stupid. Didn't realize these were all alkali metals. Yes, Lithium is the least metallic out of all of those. It's higher on the periodic table, and in the group.
