1. The Periodic Table
by Joelle Hogg

2. Discovery
• Many scientists produced some lists of
elements but the actual periodic table
didn’t arise until Dimitri Mendeleev’s
version of a table of elements
• He published an official periodic table
in 1871 but had presented a version of
his own to Russian Chemists in 1869 in
Russia

3. Why?
This is a
question
mark just fyi
• chemists had been trying to find a way
to organize elements in a way the world
could understand

4. Organization
• the periodic table is in order by the
increasing number of the elements’
mass
• also the rows of the table are called
periods and the columns groups

5. Relationship
• elements are of course all related
because they are all only made up of
one atom
• the periodic table also has groups
among it like the the metals and
nonmetals
