  • diamondboy
can u draw the lewis structure?
anonymous
  • anonymous
No..
diamondboy
  • diamondboy
ok so lets walk through that
Photon336
  • Photon336
first off do you know how to draw the lewis structure? You need to look at the number of valence electrons, beryllium has 2 valence electrons, and chlorine has 7, |dw:1442608897751:dw|
anonymous
  • anonymous
Okay...
diamondboy
  • diamondboy
so can u do it now?
Photon336
  • Photon336
could you draw out the lewis structure for both chlorine and beryllium @WhatEven ?
anonymous
  • anonymous
No...
diamondboy
  • diamondboy
ok so lets do it this way....how many valence electrons does Cl has
diamondboy
  • diamondboy
*have
anonymous
  • anonymous
7.
diamondboy
  • diamondboy
ok...multiply it by 2
Photon336
  • Photon336
|dw:1442609468445:dw|
diamondboy
  • diamondboy
with that in mind how many valence electrons does Be have
anonymous
  • anonymous
I remember this a little, In order for an atom to bind to another it must have 8 electrons in it's outer shell/ octet so chlorine is a (can't remember the name) atom and will bind with an atom that has one making that atom a (Can't remember the name) atom

|dw:1442609786259:dw|
diamondboy
  • diamondboy
|dw:1442609885669:dw|
diamondboy
  • diamondboy
that's the lewis structure
diamondboy
  • diamondboy
and so it has a molecular geometry of? (Hint: CD2 = linear. Note: CD could be any atom)
anonymous
  • anonymous
Uhmm, one sec lemme look at the question again
anonymous
  • anonymous
I don't know what linear etc would look like...
Photon336
  • Photon336
@whateven Linear looks like this |dw:1442610553443:dw|
anonymous
  • anonymous
So is my answer linear
anonymous
  • anonymous
Or no?
Photon336
  • Photon336
why do you think it's linear?
Photon336
  • Photon336
that's the answer but why
anonymous
  • anonymous
Because its two circles with one in the middle o.o
Photon336
  • Photon336
@WhatEven |dw:1442611050752:dw|
Photon336
  • Photon336
@WhatEven Lone pair means a pair of electrons that does not participate in bonding for example. in NH3 ammonia. |dw:1442611152163:dw| Lone pairs cause the angles to become smaller between atoms and change the shape. |dw:1442611209066:dw| Because Beryllium does not have any lone pairs, the bond angle is 180 say if it did. |dw:1442611259250:dw|
diamondboy
  • diamondboy
well...just know that any chemical formula that has the form|dw:1442611295036:dw|
anonymous
  • anonymous
Yes!^ Like that
diamondboy
  • diamondboy
then it's linear
anonymous
  • anonymous
Wait
anonymous
  • anonymous
those new ones confused me
diamondboy
  • diamondboy
which one do u understand well?
anonymous
  • anonymous
Linear
anonymous
  • anonymous
So what about this one?

Photon336
  • Photon336
@WhatEven draw it out for us and show us what it is here and tell what you think it is I think @diamondboy did a good job explaining the concepts.
anonymous
  • anonymous
I can draw linear like this, I understand it that way, but I need to know how the other,s would look and what number of valence electrons they have and I don't know either..
Photon336
  • Photon336
you can at least try and draw it
diamondboy
  • diamondboy
@WhatEven okay we can do this together...I am currently working on my assignment but I would put it on hold so we can do this.
anonymous
  • anonymous
Well tell me how to set them up, like two dot's out side a line And I don't want to stop you from your school...
diamondboy
  • diamondboy
I don't want to leave u without the understanding of how this works. Are u with me?
anonymous
  • anonymous
I am
diamondboy
  • diamondboy
So how mand valence electron does hydrogen and oxygen have
diamondboy
  • diamondboy
*y
anonymous
  • anonymous
One sec
anonymous
  • anonymous
Oxygen 6
diamondboy
  • diamondboy
ok
diamondboy
  • diamondboy
what about Hydrogen
diamondboy
  • diamondboy
Ok so hydrogen has 1 and altogether we have 7 valence electrons all we need to do is distribute them around H2O
diamondboy
  • diamondboy
|dw:1442612913257:dw| now do u see it?
anonymous
  • anonymous
I believe so, but I thought it had to have 8?
diamondboy
  • diamondboy
well it doesn't go like that for all of them
diamondboy
  • diamondboy
for example oxygen in this formula is electron deficient. Assuming H had more than 1 valence electron we would have made use of double bonds to get Oxygen in octet or 8
diamondboy
  • diamondboy
now can u fill the diagram and let me see
anonymous
  • anonymous
|dw:1442613121082:dw| so seven right?
diamondboy
  • diamondboy
yep but u are almost there
diamondboy
  • diamondboy
like I said hydrogen has just 1 valence electrons so give each hydrogen 1 and the rest to oxygen
anonymous
  • anonymous
Ohh Ok so|dw:1442613400403:dw| ?
diamondboy
  • diamondboy
|dw:1442613495727:dw|
diamondboy
  • diamondboy
do u see what I am saying now?
diamondboy
  • diamondboy
so now to make hydrogen happy we need to give it one more electron to make it happy. |dw:1442613643525:dw|
anonymous
  • anonymous
Yes, but why do they have to separate that way? Why not evenly?
diamondboy
  • diamondboy
hmm like why don't they have even distribution of electrons?
anonymous
  • anonymous
Yes
diamondboy
  • diamondboy
ok because for hydrogen all we need is just one electron to fill it's octet...its d only wierd kid on the periodic table
diamondboy
  • diamondboy
so when it bonds it takes only one electron to make itself ok.
diamondboy
  • diamondboy
As for oxygen....it would have loved to be octet or 8 but it's hooked up to the wrong element
anonymous
  • anonymous
I (sorry I have to go I'll coto leave this open and come back
diamondboy
  • diamondboy
ok we forgot that the total number of valence electron is 8 not 7 because we have 2 hydrogen's or with each one having one valence electron |dw:1442613901250:dw|
