There are a total of 118 elements in the periodic table. Nearly 120 chemical elements have now been identified.In 2016 four more elements were added into the periodic table. The number of protons in an element gives the atomic number of the element
Periodic table is the organized array of all the chemical elements in order of increasing atomic number—i.e., the total number of protons in the atomic nucleus.
