Foreign Scientists and Their Contribution in Chemistry
Antoine Lavoisier was born in the year 1743 to a wealthy family and inherited a huge fortune at the age of five after the demise of his mother.
A noble man by profession has contributed a lot in both chemical and biological science.
Antoine Lavoisier is the first person to term Oxygen and Hydrogen and also was the first one to establish that sulphur is not a compound but an element.
He was the first person to determine that air is a mixture of nitrogen and oxygen.
His other contribution includes researches in the field of quantitative chemistry.
“Amedeo Carlo Avogadro”

Amedeo Carlo Avogardro was born in Italy in 1776 and his main contribution was in the field of relative molecular mass.
He established the relationship between the masses of different gasses at the same volume and their corresponding molecular weights.
His more noted contribution was the Avogadro law where he established the molar particle number to be exactly equal to 6.022 x 1023.
“Niels Henrik Bohr”

Niels Henrik Bohr was born in the year 1885 in Copenhagen to a professor of physiology Christian Bohr.
Niels Bohr grew up in an atmosphere conducive for academic brilliance.
He contributed in the understanding of the atomic structure and the quantum mechanics related to it.
“Robert Millikan”

Robert Millikan the American Physicist was born in 1868 has contributed in the field of photoelectric effect and is more famous for his work on the mass of electron and its charge by the charge oil droplet in an electric field method.
This contribution played a vital role in the foundation of chemical studies in later years.
“Ernest Rutherford”

Ernest Rutherford, the New Zealand born (1871) British scientist contributed a lot in chemical studies by discovering the three radioactive particles alpha (positive), beta (negative) and gamma (neutral) rays by passing a radioactive ray through a magnetic field and then categorizing these according to the deflection by

    Werner Heisenberg worked right around the time of James Chadwick. He discovered that neutrons, electrons and protons do not have a direct connection. His discoveries introduced atomic physics. He found out that the number of neutrons are not always the same. One thing led to another and the discoveries of Heisenberg helped to create the nuclear bomb.…

    Although Joseph John (J.J.) Thomson (1856 - 1940) was mainly a physicist, his discoveries are closely connected to the chemical community. Thomson used Crookes high vacuum cathode ray tube in his discovery of electrons. He found the green beam produced by the cathode ray tube was a completely negatively charged material. Experimenting with different electrically charged plates and magnets in the cathode ray tube and observing the deflection of the rays he had enough evidence to say that particles smaller than atoms existed. By doing this experiment multiple times he compiled enough data to conclude that the mass of one of these particles, which he called an electron, was lighter than an atom of hydrogen by around 2,000 times. He also found the ratio of charge to mass (e/m) would be the same for any electron.…

    Six scientists were chosen to see which one had made the greatest contribution to our current understanding of the atom’s structure. Our knowledge of an atom’s appearance and structure have evolved from years and years of development and contribution from many different scientists. Scientist Ernest Rutherford had been the best contributor to the understanding of the atomic structure. Why Rutherford was chosen is because his work had information on protons, neutrons, and electrons, the main components that make up the atom, showed what the atom looks like when the three are put together, and had also been the discoverer of the nucleus which is the one of them most important parts of the atom’s structure.…

    He wrote many papers and the subjects of the papers he published reflect his amazing scientific versatility. He published about 350 publications in the fields of: experimental determination of the structure of crystals by the diffraction of X-rays and the interpretation of these structures in terms of the radii and other properties of atoms; the application of quantum mechanics to physical and chemical problems, dielectric constants, X-ray doublets, momentum distribution of electrons in atoms, rotational motion of molecules in crystals, Van der Waals forces, etc., the structure of metals and intermetallic compounds, the theory of ferromagnetism; the nature of the chemical bond, including the resonance phenomenon in chemistry; the experimental determination of the structure of gas molecules by the diffraction of electrons; the structure of proteins; the structure of antibodies and the nature of serological reactions; the structure and properties of haemoglobin and related substances; abnormal haemoglobin molecules in relation to the hereditary haemolytic anemias; the molecular theory of general anaesthesia; an instrument for determining the partial pressure of oxygen in a gas; and other…
