The Periodic Table has 7 periods and 18 groups.
The periods are in a horizontal line and the groups are in a straight line like up to down.
There are over 100 periods in the periodic table. Divided into various groups: Alkaline Earth Metals, Alkaline metals, transition metals, halogens and noble gases.
The periodic table consists of elements, not tables. It consists of 118 elements, from Hydrogen as 1, to Ununoctium at number 118.
There are 80 solids

Period number describes the total number of shells. There are 7 periods in periodic table.
Periods on the periodic table go across and are based on the number of unexcited electrons increasing as you read across. Groups on the periodic table are read down the table and share the same number of valence electrons.
