1. A Guide to The
Periodic Table of
Elements
By Maribeth Villanueva
Period 8
2. How did The Periodic
Table of Elements come
to be?
In 1869, a scientist named Dmitri
Mendeleev arranged 63 known elements
according to their atomic mass.
3. Who was Dmitri
Mendeleev?
Dmitri Mendeleev was a
Russian scientist born in
Siberia in 1834 and died in
1907.
While writing his textbook, Principles of
Chemistry, Mendeleev found that if you arrange
the elements in order of increasing atomic mass,
their chemical properties demonstrated definite
trends.
4. How does this thing
work?
The table is organized in a way to make
it very easy and accessible to use, but the
key words to fully understand are group,
period, atomic number, atomic symbol,
and element symbol.

12. Example of an Element:
Name: Vanadium
Atomic Number: 23
Symbol: V
Atomic Mass: 50.9415
What is vanadium used for?
Vanadium's primary use is as an
alloy for tools and construction
13. Example of an Element:
Name: Beryllium
Atomic Number: 4
Symbol: Be
Atomic Mass: 9.012182
What is Beryllium used for?
Beryllium copper alloys are
useful for electrical contacts
because they retain the spring
force.
14. Example of an Element:
Name: Carbon
Atomic Number: 6
Symbol: C
Atomic Mass: 12.0107
What is it used for?
Drinks - By mixing with oxygen in the
form of Carbon Dioxide it allows for the
bubbles in soda.
