2. He created the first periodic table
Dmitri Mendeleev
Russian Scientist who discovered a set of patterns that applied to all of the elements in regards to
atomic mass
their ability to bond
He created the first periodic table

3. Periodic Table
An arrangement of the 100 elements showing a repeating pattern of their properties
The properties of an element can be predicted by its location on the periodic table.
Arranged in order of increasing _____________.
Mendeleev organized his periodic table in order of increasing _____________: The AVERAGE of all of the isotopes an element.

4. The Periodic Table
Elements are organized into rows and columns based on their atomic number.

6. Atomic Numbers, Symbols and Mass
_____________ (the smaller number) is the number of protons in the nucleus.
_________ 47 Ag
Silver
________
____________ is the all the protons and neutrons added together.

7. Periods Groups or Families
Elements in a period are not alike, but gradually change as you move from left to right.
Groups or
Families
Elements
in a group have very
similar characteristics
i.e. bonding, reactivity, valence electrons

8. Periodic table is also arranged in classes: Metals, Semi-metals, Non-metals, and Inert gases
