PART 1: ATOMIC NUMBER
An element’s position in the periodic table is determined by its atomic number. The
numbering system begins with hydrogen (H), atomic number 1, in the upper left
hand corner and moves from left to right. The numbers skip any blank spaces in
between, so Helium (He) has atomic number 2. The numbers then jump back to left
again, so lithium (Li), atomic number 3 is next.
TO DO: record the atomic numbers 1, 2, 3 for hydrogen, helium and lithium,
respectively on the periodic table below. Write in the atomic numbers for beryllium
(Be), and boron (B) following the same pattern. Continue down the horizontal row,
from carbon (C) to neon (Ne).
Which element has the largest atomic number?
a) carbon (C) or silicon (Si) _______________________________
b) silicon (Si) or phosphorous (P) ___________________________________
c) beryllium (Be) or sodium (Na) ____________________________________
d) barium (Ba) or Actinium (Ac) _______________________________________
PART 2: EVERY ELEMENT IS A PART OF A GROUP
The correct name for each vertical column in the periodic table is a group. There are
18 groups in the periodic table, as you can see. The lanthanides and actinides do not
follow in this grouping method.
TO DO: Locate the elements in the SECOND GROUP FROM THE LEFT. Record the
symbols for these elements in the periodic table below.
Which element from this group has the largest atomic number? ______________________
Which element would you expect to have the largest atomic mass? _____________
1. List the symbols for the other elements found in the same group as:
a) aluminum (Al) _____________________________________________________
b) potassium (K) ______________________________________________________
c) lead (Pb) _________________________________________________________
2. Using 8 different colors, shade in the first 2 groups to the left side of the table and
the 6 groups to the right.
3. Create a key showing the colors you used to shade in the following special groups.
Alkaline Metals
Alkaline Earth Metals
Halogens
Noble Gasses
PART 3: EVERY ELEMENT IS A PART OF A PERIOD
The horizontal rows of the periodic table are called periods.
TO DO: Write the symbols for the elements in the first three periods. Then, using 7
different colors, shade in the 7 different periods on the periodic table below. Don’t
forget the lanthanides and actinides!
1. Write the symbols for all of the liquids on the periodic table. Circle them. Do
any of them appear in Period 2 or 3? ____________
2. Find all of the gasses in the periodic table and with a black pencil crayon,
outline each of them on the above table.
3. In the table below, indicate which gasses are located in each of the periods.
Your table will not have elements in every blank space.
Period 1
Period 2
Period 3
Period 4
Period 5
Period 6
Period 7
PART 4: USING THE PERIODIC TABLE
Using the periodic table, answer the following questions in the spaces provided.
1. Write the name and symbol of the element that is located in:

Group 15, Period 5 _____________________________________________

Group 18, Period 3 _____________________________________________

Group 8, Period 4
_____________________________________________
2. Write the name and symbol of the element that is:

The noble gas in period 2
________________________________________

The alkali metal in period 6
________________________________________

The halogen in period 4
________________________________________
3. Name the 2 elements that would probably be the most similar (physically
and chemically) to:

Barium
______________________________________

Chlorine
______________________________________

Silver
______________________________________

Tin
______________________________________
4. Provide the name and symbol for the element that:

Is in the same family as potassium but reacts more readily ________________

Has an atomic number 2 greater than that of carbon ________________________

Is a non-metal that exists as a liquid at room temperature _________________

Is a halogen that is a solid at room temperature ______________________________

Is the noble gas with the second highest atomic number ____________________
