Help quick! I need the Lewis Dot Structures for LiBr, MgO, KCl, and AlP!?

Question

The yahoo editing thing doesn't let you do it, so maybe do it in paint or paint shop pro and then upload it??? i'm not understanding this at all.

Answer 1

The formatting on this is going to be difficult, because Yahoo!Answers likes to cut out leading spaces. So what I'm going to do is just put bonding electrons between the atoms and non-bonding on the ouside faces, and you can distrubute those outside dots into more separated pairs in your diagram.

Li : BR : : :

Mg : : O : :

K : Cl : : :

Al : : : P :

The main issue with problems like these is distinguishing bonding electrons from non-bonding ones. You can look each element up on the periodic table to see how many valence electrons each has. These four examples all work out well because the two atoms always add up to the desired eight.

This means one atom is going to share all its electrons, putting one in each bond, while the other one (the one with more) will have extras left over after matching those bond electrons, as you can see above. Li-Br and K-Cl are essentally the same. The only curve you've been thrown is Al-P, which has an unusual (but not unheard of) triple bond.

Answer 3

Mgo Lewis Structure

Answer 4

It is difficult to draw L.E.D. using this edit program.
Li has no electrons around it but Br has 4 sets of 2 at each of the four postions (Left, Right, Top, Bottom)
Mg no electrons but oxygen like Br above (4 sets of 2 at each of the four postions.
KCl - like LiBr. K no electrons, Cl 4 sets of 2 each.
Al no electrons but P with 4 sets of 2 each. Al donates 3 electrons to P to complete its outer shell with 8 electrons.
