The document summarizes the periodic table, including who created it and how elements are organized. Dmitri Mendeleev and Lothar Meyer independently developed the periodic table around the same time, but Mendeleev published his first. The periodic table arranges elements by atomic number and groups them according to metal/non-metal properties and families such as noble gases, halogens, and transition metals. It also provides examples of the elements boron, aluminum, and beryllium, where they are found and some of their uses.

some disagreement
between scientists
about who created
the Periodic Table.
Both Lothar Meyer and Dmitri Mendeleev
had the same results at the same time while
working independently, but Mendeleev’s
became published first.

5. Boron
=
✴ It is found in mines in Turkey and the
USA.
✴ It is used in making fiberglass, ceramic
glazes, laundry bleach, fertilizer, and
herbicides.

6. Aluminum
=
✴ Aluminum isn’t found in mines, it has
to be extracted from cryolite.
✴ It is used in making aircrafts, making
decorative wrapping, and packaging.

7. Beryllium
=
✴ Beryllium is found in mineral compounds.
✴ It is used in the making of zirconium, it is
used to make springs for swiss watches, and it is
used for making tools.
