Covalent Bonding: Boron's 5 Valence Electrons

[kassandra]

More questions lol.

Ive looked this up and still can't get a clear answer.

Lets say you have Boron...this atom has 5 valence electrons.

I know that it can just have 3 covalent bonds with one other atom of Boron like this:
:B
lll
B

But could it not just have a single convalent bond with three separate atoms of Boron or any other atom for that matter like this:
B
l
:B-B
l
B


or this:
Li
l
:B-H
l
Rb

or even this:
Be
ll
:B-H

I have an even more complicated questions but I need the answer to this one first lol.

Thanks

no B has 3 valence electrons, it is in Group IIIA (or 13). (It does have is 5 electrons but that includes 2 core electrons that are not involved in bonding)

Is your next problem trying to draw a Lewis structure of a boron compound?

No, just trying to figure out everything 100%
I only had one set of questions and they are done. Now were just going over the chapters and i don't want to get behind

well what is Boron bonding with?
If its previously stated then i apologize i was not paying attention
