Question

________ was the first one to formulate the modern periodic table of elements

​

Answer 1

Answer:

The periodic table is an arrangement of the chemical elements, organized on the basis of their atomic numbers, electron configurations and recurring chemical properties. Elements are presented in order of increasing atomic number. The standard form of the table consists of a grid with rows called periods and columns called groups.

2016: current form, 118 known elements

The history of the periodic table reflects over two centuries of growth in the understanding of the chemical and physical properties of the elements, with major contributions made by Antoine-Laurent de Lavoisier, Johann Wolfgang Döbereiner, John Newlands, Julius Lothar Meyer, Dmitri Mendeleev, Glenn T. Seaborg, and others.[1][2]

Answer 2

⁂  Answer ⁂

Dimitri Ivanovich Mendeleev was the first one to formulate the modern periodic table of elements.

✪ More To Know ✪

• Dimitri Ivanovich Mendeleev's  periodic chart included 63 known elements arranged according to increasing atomic weight

• Mendeleev also left spaces for as yet undiscovered elements for which he predicted atomic weights.

• Later, Henry moseley developed the first modern periodic table by basing the element sequence on atomic number (number of protons) rather than on atomic mass.
