Please can someone explain how to draw them, i am so confused, the more i read about it, the more i get confused.
i am having problems understanding how to draw lewis dot structures for
species such as Ca3Po4,
so do i?
pO- Ca-Ca-Ca -Po
l l
Po Po
does it have to be in order??? and where do the dots go?
and how many, okay so i go to the periodic table and look up
what group they are under so H would be one so it gets one dot,
but do i put how many dots they need around each one???
please can someone explain this , i will be extremely appreciative.
thank you

Draw PO43- first.

Mitch probably meant PO43-.
-
and studygirl prolly meant Ca3(PO4)2

Let me try...

This topic went off the hook. QUICKLY lol...
Looks good Winga. Even got the stereochemistry in there. Studygirl probably realizes that that's NOT a lewis dot structure - so I won't need to point that out ;D
P.S. I AGREE that there is not much good info on Leiws Dot Structure Tutorial stuff anywhere...I honestly was confused, until midway through first-year university :-[
There's so many exceptions...and little nuances and intricacies...so keep at it. One of the best places I've found, is from a professor Chieh at my University. Check it out, unless you've already seen it: http://www.science.uwaterloo.ca/~cchieh/cact/c120/dotstruc.html (http://www.science.uwaterloo.ca/~cchieh/cact/c120/dotstruc.html)
Best of luck, and we're here for ya.
Awwwwwwww lol
