How many peroids are in the periodic table of elements?
There are 18 periods in the periodic table. The periods are divided according to the chemical properties of elements. Elements in a group have similar properties.
How many known elements are made up of the period as of 2015?
As of 2015, there are 118 known chemical elements on the periodic table. The elements are organized into periods, which are the horizontal rows of the table. There are seven periods in total, each containing a varying number of elements. The first period contains 2 elements, while the second and third periods contain 8 elements each, and the number increases in subsequent periods.

How many periods does Periodic table contain?
There are a total of 18 groups on The Periodic Table of Elements.
Why are the elements on the periodic tables separated into periods?
The elements on the periodic table are separated into periods based on the number of electron shells they have. Elements in the same period have the same number of electron shells, which influences their chemical properties and reactivity.
How many elements make up the periodic table?
118 elements.
Why some of the periods have different numbers of elements?
The early periods have less elements because they are filling up energy levels which hold only a few electrons. The later periods contain elements with electrons in levels with a greater capacity.
What relationship exists between elements and periods according to the periodic law?
The relationship between elements and periods according to the periodic law is that elements are arranged in periods based on their atomic number and properties. Elements in the same period have the same number of electron shells, while elements in the same group have similar chemical properties.
