Dmitri Mendeleev created the periodic table by arranging elements in order of increasing atomic mass, finding that elements' properties repeated periodically. The periodic table groups elements with similar properties into columns and periods. The periodic law states that when elements are arranged by increasing atomic number, their chemical and physical properties repeat periodically, with metals usually on the left and nonmetals on the right.

2. Dmitri Mendeleev
• Founder of the Periodic Table of Elements.
• Dmitri wrote the elements down in order of
increasing mass and found a pattern of repeating
properties.
• He grouped elements in columns (by similar
properties) and in periods.

3. Quick facts:
• Many people
look at the
periodic table as
a piece of art.
• Purchasing a
periodic table
can be
expensive.
*Please not that this periodic table is not of elements
but of sucrose!

4. Periodic Law
• When the elements are arranged in
order of increasing atomic number,
there is a periodic repetition of their
chemical and physical properties.

5. • Most of the elements metals.
• Metals are to the left of the stair
steps and non-metals are to the
left.
• The first element in a group is
always an active metal, the last is
always an inactive non-metal.
