History of the Periodic Table
Dmitri Mendeleev:
• Russian chemist and teacher
•When organized elements into groups
by similar chemical properties,
he observed the periods increasing in
atomic mass. (1869)
• His organization system was
successful at predicting undiscovered
elements.
•Do you observe any inconsistencies
with his organization system?
History of Periodic Table
Henry Moseley:
•British Physicists
•Tweaked Mendeleev’s periodic table.
•When elements were placed in groups
by chemical properties, the periods
consistently increased by atomic
number. (1913)
•Current organization of elements on
the periodic table.
