Are there 120 elements?
The periodic table has proven up for the element with atomic number 118 as of now (2020), and no elements have successfully incorporated with an atomic number greater than 118. Still, extended periodic table theories predicted about chemical elements beyond these 118 elements.
Why there are 7 periods in Mendeleev periodic table?
Mendeleev created a periodic table of all the elements that were known at the time. The rows of the table, called periods, each contained eight elements that increased in atomic mass from left to right. The columns of the table, called groups, contained elements with similar properties.
