Step 1: Find the Central Atom
Central atom is: N
AB3E
Molecular Shape of NH3
Look your line bond structure on
page 1.
H-N-H

Step 3: Choose the ABE classification
Circle the correct AB E, notation.
Recall, we use (A) to represent the
central atom, (B) to represent the
number of atoms bonded to the central
atom, and (E) to represent the number
of lone pairs
AB₁E3 AB₁E₂

Step 5: Use the Molecular Shape
table from your notes to draw the
ball and stick representation

A, B, E, = A ₂ E
Step 2:
Count number of atoms bonded to the central
atom (B)
# of atoms bonded to central atom = B = 3

Central a tom)
Ilone pair E
Count number of lone pairs on the
central atom (E)

Step 4: Use the Molecular Shape Table from
your notes to select the molecular shape and
bond angles.
Molecular Shape=

-Pyramidal !!
Step 6: Determine Polarity
Is the central atom surrounded by identical
electron groups?
Circle one: yes no
If the answer was yes, then the molecule is
nonpolar. If the answer is no, then the molecule
is polar.
Is the molecule polar?
Circle one: yes no
