The periodic table has 7 periods.
110 to be exact
5
periodic table stands for all the elments scientist have found till today. Example: gold, silver, oxegon, carbon dioxide,ect.
Elements in the same family (group) on the periodic table have the same number of valence electrons and hence they have similar properties and reactivities.
A period is a row in the periodic table of elements.
There are seven metalloids on the periodic table.
Groups of the Periodic Table are defined as vertical colums. There are 18 groups in the periodic table.

Technetium (43), Promethium (61), and all the transuranic elements are synthetic.
A "family" of elements means the vertical columns in the periodic table. If you look above the periodic table, there will be numbers for each row, numbered from 1 to 18. Each "family" is a column.
The noble gases viz., helium, neon, argon, krypton, xenon, radon
by their atomic number
