Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of motion, energy, force, time, thermodynamics, quantum mechanics, statistical mechanics, analytical dynamics and chemical equilibria. Physical chemistry, in contrast to chemical physics, is predominantly (but not always) a supra-molecular ...
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Chemistry. The 1871 periodic table constructed by Dmitri Mendeleev. The periodic table is one of the most potent icons in science, lying at the core of chemistry and embodying the most fundamental principles of the field. The history of chemistry represents a time span from ancient history to the present.
An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.
Jacobus van 't Hoff (1852–1911), an influential theoretical chemist and the first winner of the Nobel Prize in Chemistry.. Theoretical chemistry is the branch of chemistry which develops theoretical generalizations that are part of the theoretical arsenal of modern chemistry: for example, the concepts of chemical bonding, chemical reaction, valence, the surface of potential energy, molecular ...
Johan Erik Rydqvist. Baron Jöns Jacob Berzelius (Swedish: [jœns ˈjɑ̌ːkɔb bæˈʂěːlɪɵs] [1] (20 August 1779 – 7 August 1848) was a Swedish chemist. In general, he is considered the last person to know the whole field of chemistry. [2] Berzelius is considered, along with Robert Boyle, John Dalton, and Antoine Lavoisier, to be one of ...
Chemical kinetics. Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is different from chemical thermodynamics, which deals with the direction in which a reaction occurs but in itself tells nothing about its rate.
Robert Boyle FRS [2] (/ b ɔɪ l /; 25 January 1627 – 31 December 1691) was an Anglo-Irish [3] natural philosopher, chemist, physicist, alchemist and inventor. Boyle is largely regarded today as the first modern chemist, and therefore one of the founders of modern chemistry, and one of the pioneers of modern experimental scientific method.
