Hi, this is Dr.B.  We're going to draw  the lewis
dot structure for carbon.  Carbon is
right here on the periodic table.
So that's what will be working with.
The first thing we want to do is figure out
how many
valence electrons each group here has.  And the easy way to do that is start with eight, seven
six
five
four
you skip all the transition metals
your practical might have this written
on it already or it might have a
thirteen and fourteen.
Once you know that
you know how many valence electrons are going to be in that group.
So we looked at carbon right here
and that says it has four valence electrons.  So that makes sense
so all we have to do now is draw our
carbon
right here
and let's put something on valence electrons around it.
so we start out we put two right here
this pair
on the side
and then we go three, four.
So one, two, three, four.
Carbon is in group four
right here so it has four valence
electrons
and you're done
that's the Lewis dot structure for
Carbon.
This is Dr. B and thanks for watching.
