This is a timeline of subatomic particle discoveries, including all particles thus far discovered which appear to be elementary (that is, indivisible) given the best available evidence. It also includes the discovery of composite particles and antiparticles that were of particular historical importance.
The first to utilize the electric spark to produce an explosion of hydrogen and oxygen, mixed in the proper proportions, to produce pure water. 1784: Henry Cavendish: Discovered the inductive capacity of dielectrics (insulators) and, as early as 1778, measured the specific inductive capacity for beeswax and other substances by comparison with ...
Carbon was discovered in prehistory and was known in the forms of soot and charcoal to the earliest human civilizations. Diamonds were known probably as early as 2500 BCE in China, while carbon in the form of charcoal was made by the same chemistry as it is today, by heating wood in a pyramid covered with clay to exclude air.

First, he used a gamboge soap-like emulsion, second by doing experimental work on Brownian motion, and third by confirming Einstein's theory of particle rotation in the liquid phase. [22] In 1937, chemist K.L. Wolf introduced the concept of supermolecules (Übermoleküle) to describe hydrogen bonding in acetic acid dimers.
It is thought that the first person to aerate water with carbon dioxide was William Brownrigg in the 1740s. [3] [4] Joseph Priestley invented carbonated water, independently and by accident, in 1767 when he discovered a method of infusing water with carbon dioxide after having suspended a bowl of water above a beer vat at a brewery in Leeds ...
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.
1781 Joseph Priestley creates water by igniting hydrogen and oxygen; 1800 William Nicholson and Anthony Carlisle use electrolysis to separate water into hydrogen and oxygen; 1803 John Dalton introduces atomic ideas into chemistry and states that matter is composed of atoms of different weights
In 1820 Faraday reported the first synthesis of compounds made from carbon and chlorine, C 2 Cl 6 and CCl 4, and published his results the following year. [ 41 ] [ 42 ] [ 43 ] Faraday also determined the composition of the chlorine clathrate hydrate , which had been discovered by Humphry Davy in 1810.
