Example Problem 1

• Fluorine has an Atomic Number of 9. Draw an atom
  of fluorine. How and why will fluorine react?

3
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, fluorine will tend to 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?

5
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 atoms and be relatively
inert

Example Problem 3

• Hydrogen has an Atomic Number of 1. Draw an atom
  of hydrogen. How and why will hydrogen react?

7
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 to
bind with atoms that have one electron to donate

Example Problem 5

• Carbon has an Atomic Number of 6. Draw an atom
  of carbon. How and why will carbon react?

11
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 bonds.
To do this it 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?

13
Example Problem 2

• Oxygen has an Atomic Number of 8. Draw an atom
  of oxygen. How and why will oxygen react?

Since atoms are 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.
