## Main Question or Discussion Point

Greetings.

I am having some problems with understanding polarity.

I will start the problems one by one, whenever one problem is solved i will go to the next one.

Ok, here is the first one.

I am unable to understand why we say that BeF

Any help for me to understand this would be appreciated.

Thanks.

_{2}is**not**polar. When i try to analyze it, i think that we should consider it as a molecule with two negative poles, and some positive charge at the middle (and therefore, polar, right ?).Any help for me to understand this would be appreciated.

Thanks.
