Answer 1

The correct answer is Alfred Werner.

Key Points

In 1893, the Swiss chemist, Alfred Werner, was the first to understand the molecular structures of inorganic substances – chemical compounds that do not contain carbon.
Werner asserts that the attraction forces come uniformly from the centre of the atom rather than being associated with any particular directions in the atom. He clarified the structures of substances by assigning a new coordination number to an atom's bonds.
The octahedral structure of transition metal complexes was proposed by Alfred Werner, who was awarded the Nobel Prize in Chemistry in 1913.
Modern coordination chemistry's foundation was created by Werner and he was the first to receive the Nobel prize for inorganic chemistry.

William Ramsay, who won the 1904 Nobel Prize in Chemistry, contributed to the creation of the noble gases as a new group in the periodic table.
In 1943, George de Hevesy, a radiochemist from Hungary, won the Nobel Prize in Chemistry for discovering the radiotracer concept.
John Dalton was an English chemist, physicist, and meteorologist best known for his work on human optics and for introducing the atomic theory to chemistry.
