>In this video, we're going to
practice drawing covalent bonds,
-
so we're going to practice
drawing Lewis structures.
-
Lewis structures...
-
...and we need Lewis structures
when we form covalent bonds.
-
So reminder, if I have
all over here, my nonmetals,
-
plus a nonmetal,
-
the the type of bond, the thing
that holds those two atoms together
-
is going to be called a covalent bond.
-
Okay, so let's get started.
-
All of these examples,
my very first element is a group 4,
-
so I find my group 4,
that's over on the right side,
-
and I have four valence electrons,
-
and it forms four bonds.
-
So carbon has four valence electrons.
-
(You can picture it
like this if you'd like.)
-
It has four valence electrons,
and to get to the eight,
-
it needs to form four bonds.
-
Okay, and the same thing for Si,
-
the same thing--
