Bohr Diagrams Review
C
1) Draw a nucleus with
the element symbol
inside.
2) Carbon is in the 2nd
period, so it has two
energy levels, or shells.
3) Draw the shells around
the nucleus.
Bohr Diagrams Review
C
1) Add the electrons.
2) Carbon has 6
electrons.
3) The first shell can only
hold 2 electrons.
Bohr Structure
C
1) Since you have 2
electrons already
drawn, you need to
add 4 more.
2) These go in the 2nd
shell.
3) Add one at a time starting on the right
side and going counter
clock-wise.

Worksheet
1) Check your work.
2) You should have 6 total
electrons for Carbon.
3) Only two electrons can
fit in the 1st shell.
4) The 2nd shell can hold
up to 8 electrons.
5) The 3rd shell can hold
18, but the elements in
the first few periods
only use 8 electrons.

Lewis Structure Practice
Wed/Thurs 10/30-10/31 for
27 Points
Lewis Structures Review
• Find out which group
(column) your element is
in.
• This will tell you the
number of valence
electrons your element
has.
• You will only draw the
valence electrons.

Lewis Structures Review
1) Write the element
symbol.
2) Carbon is in the 4th
group, so it has 4
valence electrons.
3) Starting at the right,
draw 4 electrons, or
dots, counterclockwise around the
element symbol.
Lewis Structures Review
1) Check your work.
2) Using your periodic
table, check that
Carbon is in the 4th
group.
3) You should have 4
total electrons, or
