Question

How did Johan Wolfgang Döberenier organize elements on the periodic table?

a) By atomic number

b) By atomic mass

c) By reactivity

d) By color

Answer 1

Dmitri Mendeleev organized the elements on the periodic table based on their atomic number and shared chemical and physical properties. Therefore, the correct option is A.

Step-by-step explanation:

Johan Wolfgang Döberenier did not organize the elements on the periodic table. The periodic table was actually created by a Russian scientist named Dmitri Mendeleev in 1869. Mendeleev organized the elements according to their atomic number and their shared chemical and physical properties. He arranged the elements in rows and columns based on these properties, creating a repeating pattern known as the periodic table.
