Answer: The correct order is:

Lavoisier, Dobereiner, Newlands, Mendeleev, and Moseley

Explanation:

In 1789, the Lavoisier given the periodic table distribution by placing the elements into two groups of metals and non metals.

In 1817, the Dobereiner attempted to classify elements in a periodic table by placing them group of three with similar chemical and physical properties. these groups were named as triads.

In 1864, the Newlands classified total 62 elements into eight groups according to their respective physical properties. And were also known as Law of Octaves.

In 1869, the Mendeleev classified the periodic table on the basis of atomic mass. In which elements were arranged in increasing order of their atomic masses.

In 1913, Moseley classified the periodic table on the basis of increasing number of protons in the elements.
