Example Problem #1
Fluorine has an Atomic Number of 9. Draw an
atom of fluorine. How and why will fluorine
react?
Example Problem #1
Fluorine has an Atomic Number of 9. Draw an
atom of fluorine. How and why will fluorine
react?
Since atoms are
stable with 8
electrons in their
valence
shell,
+
9p
fluorine will tend to
0
9n
bind with atoms
that have one
electron to donate

Example Problem #2
Argon has an Atomic Number of 18. Draw an
atom of argon. How and why will argon
react?
Example Problem #2
Argon has an Atomic Number of 18. Draw an
atom of argon. How and why will argon
react?
Since
Argon
has
a
full valence shell, it
- will not tend to
bond
to
other
+
18p
atoms and be
0
18n
relatively inert

Example Problem #3
Hydrogen has an Atomic Number of 1. Draw an
atom of hydrogen. How and why will
hydrogen react?
Example Problem #3
Hydrogen has an Atomic Number of 1. Draw an
atom of hydrogen. How and why will
hydrogen react?
Since atoms are stable
with 2 electrons in the
inner most valence
shell,
hydrogen
will
tend
+
1p
to bind with atoms that
0
0n
have one electron to
donate
Example Problem #4
Helium has an Atomic Number of 2. Draw an
atom of helium. How and why will helium
react?
Example Problem #4
Helium has an Atomic Number of 2. Draw an
atom of helium. How and why will helium
react?
Since helium has a
full valence shell, it
will not tend to
bond
to
other
+
2p
atoms and be
0
2n
relatively inert

Example Problem #5
Carbon has an Atomic Number of 6. Draw an
atom of carbon. How and why will carbon
react?
Example Problem #5
Carbon has an Atomic Number of 6. Draw an
atom of carbon. How and why will carbon
react?
Since atoms are stable
with 8 electrons in their
valence shell, carbon
will
tend
make
four
+
6p
bonds. To do this it
0
6n
may form multiple
bonds, including single,
double, or triple bonds.
Example Problem #2
Oxygen has an Atomic Number of 8. Draw an
atom of oxygen. How and why will oxygen
react?
Example Problem #2
Oxygen has an Atomic Number of 8. Draw an
atom of oxygen. How and why will oxygen
react?
Since atoms are
-
-
-
-
-
8p+
8n0
- -
stable with 8
electrons in their
valence shell, oxygen
will tend make two
bonds. To do this it
may form two single
bonds or one double
bond.
