Aristotle disbelieved the ancient Greek theory of atoms being of different sizes, regular geometric shapes and being in constant motion. He didn't think atoms could be in constant motion in a void. He developed the theory that all matter consisted of four elements: Earth, Air, Water and Fire. There were also four qualities: dryness, hotness, coldness, and moistness. Fire was dry and hot, water was moist and cold, etc. Each of these elements move naturally in a line to their "proper place," where it will be at rest. Aristotle's theory also had two forces: conflict and harmony. Conflict was thought to cause bad things, and harmony good things. Aristotle also believed that the heavens were made of a fifth, superior element named either. Aristotle's theory was used for almost 2000 years, until after the scientific revolution, when other theories prevailed.
The atomic theory of matter can be attributed to the ideas proposed by the ancient Greek philosopher Democritus. He hypothesized that all matter is composed of indivisible and indestructible particles called atoms, which differ in shape, size, and arrangement. Democritus' atomic theory laid the foundation for modern atomic theory.
Chemists benefited from Dalton's atomic theory by gaining a better understanding of the composition and behavior of matter at the atomic level. This theory provided a foundation for modern chemistry and helped explain various chemical reactions and properties of elements.
The first theory to relate chemical changes to events at the atomic level was proposed by John Dalton in the early 19th century. Known as Dalton's atomic theory, it stated that elements are composed of indivisible particles called atoms, and chemical reactions involve the rearrangement of these atoms to form new substances.
The first modern atomic theory was proposed by John Dalton in the early 19th century. Dalton's theory stated that all matter is made up of tiny, indivisible particles called atoms, and that atoms of different elements have different masses and properties.
Dalton's atomic theory laid the foundation for understanding the concept of atomic mass units (amu) by proposing that elements are made up of indivisible particles called atoms. This theory helped scientists develop a method to measure the relative masses of atoms, which led to the creation of the atomic mass unit as a standard unit of measurement for atomic masses.
Aristotles theory stated that all substances were built from 4 elements, earth, air, fire, and water
Lavoisier is not known for an atomic theory.
when i was atomic theory i was a smart
Atomic theory was founded by John Dalton. He proved this theory in 1803.
he did not develop anything regarding the 'atomic theory' for he was against that theory.
They didn't help with atomic theory, they created it.
John Dalton first pursued research into atomic theory. He was the first person to propose the existence of the atomic structure.
He pubish is own atomic theory in 1803 developed his atomic theory by observations gathered from many experiments .
Moseley was the first to clear and scientifically justify in 1913 the atomic number studying X-ray spectra of chemical elements. But Moseley hadn't a personal atomic theory, he was not the discoverer of the atomic theory.
The Atomic Theory
They both thought the same theory but Dalton had evidence to prove it, unlike Democritus.
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
