Question

Who established atomic numbers as the basis for organizing the periodic table?

Answer 1

Henry Moseley.

Step-by-step explanation:

Hello,

Henry Moseley's work stated that it is better to organize the periodic table in the light of the atomic number (which accounts for the amount of protons and electrons) instead of the atomic mass, because atomic numbers are not arbitrarily assigned as long as they have the aforesaid physical basis.

Best regards.
