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.
