chemical and physical
properties
_________.
When was the Periodic Table
developed and who created it?
•
1869 by a man named ________________

It was developed in _____
who was a Russian chemist and inventor.
INTRODUCING THE PERIODIC TABLE
•
In his time, there were only ___________
60 elements discovered, but his
future discoveries
predicted and left room for the ________________
periodic table _________

___________.
Maybe there
are more
elements?
INTRODUCING THE PERIODIC TABLE
•
Each element on the periodic table is represented within an
element
box which contains the following basic information.
___________
atomic number (A whole number with no decimals.)
2+
oxidation number (It has a + or – sign.)
element symbol (Only the first letter is capitalized.)
element name
atomic mass
a) Draw the box
for the element
that has an
atomic mass of
107.87.
1+
(It is larger than atomic number
and always has decimals.)
