Periodic Table
• Looking at the element symbols,
see if you can spell your names.
• What other words (keep it clean)
can you make using the symbols?
• This is a challenge to see which
group is able to come up with the
most words that others do not!

How is the Periodic Table organized?
• By atomic number, the number of
protons
• In columns called groups or families
– The family names are given
• In rows called periods
– The table shows seven different periods
Periodic Law
• With the elements arranged by
atomic number, their chemical and
physical properties are found to show
a repeating, or periodic, pattern.
• Elements within a family have similar
properties.
Why are there two rows
detached at the bottom?
The periodic table skips from 56 – 72 because the inner transition metals have
been cut out. The periodic table shown above does fit on a single piece of paper,
however the boxes are too small to write the element names in them.
Why do some symbols not align
with the name?
• These elements symbols come from their
Latin names.

How does the periodic table
classify the elements?
The staircase on the right side of the
table is the dividing line between the
metals and nonmetals.
The metalloids are on the staircase.
Color your PT to show the
classification:
– metals
– metalloids
– nonmetals
