The Complete Periodic Table With Charges

Jan 30, 2018The modern periodic table of elements, or just periodic table, is a tabular representation of the identified elements (as of date 118) along with their respective symbolic name and atomic number. Thus, instead of sorting elements as per their mass number (which is so in Mendeleev periodic table), elements are arranged from left to right, according to increasing order of the atomic number.

Periodic table

In the periodic table the elements are arranged into periods and groups. A row of elements across the table is called a period. Each period has a number; from 1 to 8. Period 1 has only 2 elements in it: hydrogen and helium. Period 2 and Period 3 both have 8 elements. Other periods are longer. Elements in a period have consecutive atomic numbers.
