Question

How to find out fundamental in modern periodic table?

Answer 1

Hello mate,

Here is your answer,

The modern version of Mendeleev's periodic table now contains some 118 different elements.

In the periodic table, the number above the element's symbol is the atomic number, which represents the number of protons in the nucleus.

The atomic mass is given by the sum of the neutrons and protons.

HOPE THIS HELPS UU :)

AND STAY BLESSED.
