This is the NH2OH Lewis structure.
Nitrogen has 5 valence electrons; we have
1 for Hydrogen, we have 2 Hydrogens; plus
6 for Oxygen and one for the Hydrogen on the
end there for a total of 14 valence electrons.
Nitrogen is the least electronegative, so
that'll go in the center.
We have these H2, so let's put those H's on
either side.
We know they go on the outside of Lewis structures.
And then we see this OH up here.
That means we're probably going to have an
Oxygen, and then a Hydrogen attached to the
Oxygen.
We have 14 valence electrons.
We'll put 2 between atoms to form chemical
bonds, so we've used a total of 8.
Hydrogens only need 2 valence electrons to
have a full outer shell, so they're OK.
So we have 8, 10, 12, and then we'll go back
to the central atom, 14.
So we've used all 14 valence electrons.
At this point in the NH2OH Lewis structure,
all of the Hydrogens have 2 valence electrons.
The Oxygen has 8, so its octet is full, and
then the Nitrogen has 8 so its octet is full,
as well.
So that's the Lewis structure for NH2OH.
I'm Dr. B., and thanks for watching.
