3. How is the table organized?
As you can see the Periodic Table
is organized like a big grid.
The Table is organized into
periods going from left to right
by increasing atomic number.
It is also organized by groups
based on what elements share
chemical and physical properties.
4. How else?

Non- Metals

5. Relationships?
With where the elements lie on the table
there is a relationship to the spot they are
at.
One relationship is that they can be
grouped into areas that have similar
properties.
Another way is that they are grouped in
order of increasing atomic mass.
