This video shows how there are 92 naturally occurring elements, one
for each kind of atom, and how they are arranged into a table according
to their relative weights. It also shows how the elements are arranged
in rows and groups, the latter containing elements with similar
properties, like members of a family. The expanded table is shown, and
how this is abbreviated into the common Periodic Table. The division
between metals, semi-metals and non-metals is discussed, with notable
examples.
