They are the Alkali Metals, Alkaline Metals, Transition Metals, Metalloids, Halogens, and the Noble (Inert) Gases. There is also the lanthanide and actinide series which are known as the Rare Earth Metals.
There are a total of nine families in the Periodic Table and they are: Alkali metals, alkaline earth metals, transitional metals, boron, carbon, nitrogen, oxygen, halogens, noble gases.

By grouping the elements on the Periodic Table.
See the link below fot the IUPAC model of the periodic table of elements.
All periodic table groups contain elements with radioactive isotopes.
Families in the Periodic Table of Elements have the same amount of valence electrons.
Yes, there were elements on the first periodic table. I believe that there are still elements on the periodic table.
It is called the Periodic Table of Elements.
yes, families and groups the same meaning in the periodic table.
The vertical columns are groups or families. There are 18 such families.

The periodic table organizes the elements so that they are easy to find and it also puts them into groups or "families" of elements with similar traits.
Radioactive elements exist in all groups of the periodic table.

These names are the names of chemical elements.
The names on the periodic table of Mendeleev are the names of chemical elements.
