Question

The nineteenth century chemists arranged elements in the periodic table according to increasing

Answer 1

Answer:

Julius Lothar Meyer a German chemist organize the elements by atomic mass and grouped them according to their chemical properties

Answer 2

Answer:

Chemists in the nineteenth century organized elements in the periodic table by their increasing atomic mass.

Explanation:

Several scientists worked on building a periodic table in the 19th century that organized the elements according to their atomic mass. The number of neutrons and protons in a nucleus of an element determines the atomic mass of that element.

John Newlands who was a British chemist, was the first one to organize the elements into a periodic table with increasing atomic masses. The law of octaves was thus named after his discovery that every eight elements had similar qualities. He organized the elements into eight groupings such that leaving no gaps for unknown elements. Thus, we can see that the nineteenth century chemists arranged the elements in the periodic table according to the increasing atomic mass.
