Answer:
Atomic number represents the number of proton in periodic table
Step-by-step explanation:
All the elements in a periodic table are arranged on the basis of their size while moving from left to right.
The larger the size, the higher is the atomic number. Atomic number is equal to the total number of protons present inside the nucleus of atom of an element.
Thus, indirectly atomic number represents the total number of protons.
Hence, atomic number represents the number of proton in periodic table
