Practice-The Periodic Table
TEKS 8.5C interpret the arrangement of the Periodic Table, including groups and periods, to explain how properties are used to classify elements
TEKS 8.5B identify that protons determine an element’s identity and valence electrons determine its chemical properties, including reactivity
The modern periodic table was created by Russian chemist, Dmitri Mendeleev.
Elements are represented on the Periodic Table with chemical symbols.
Si
NaFe
OCH
e
The elements are arranged from left to right based on their atomic number.
The atomic number
comes from the number of protons present in
stable atoms of that
element.
Protons determine the element’s
identity!!
Here is the structure of the Periodic Table…
Columns
The columns on the Table are called groups.
The groups arenumbered from 1-18.
Elements within a group have very similar properties.Find this symbol on your Periodic Table:
GROUPS
Draw an arrow to show the direction of the groups on
the Periodic Table!
Which way to the groups go?
VERTICAL
Periods
The rows on the Periodic Table have meaning as
well.
The rows are called periods.
Left to right is the
(period)
Next to the periods, draw an arrow to show the
direction of the periods.
Across any period, the properties of
elements gradually change. For
example, as you move from left to right across the
table, atoms tend to become smaller in size, but larger in
mass.
HORIZONTALWhich way do the periods
go?
KEYNotice the box
at the top of the Periodic Table.
This is a key that tells us
what all of the symbols and
numbers mean.

Do the following on your key on your Periodic
Table.Atomic number -CircleName = chemical symbol = element symbol-Highlight
Atomic mass- Box
Elements are classified into three large groups on the Periodic Table. The groups are ……
Major Groups
MetalsOn the left and bottom
Non MetalsOn the Right
Metalloids in the Middle along the solid line
Application: Using the Periodic Table in your Journal
Color the three groups on your Periodic Table and make a
key.
Metals = blueNonmetals = greenMetalloids = yellow
No colore No Color
Blue 1-12 and bottom 2
Along jagged line Yellow
On Right Green 14-18
