道尔顿 (dalton,Da)是一个 非国际单位制 的 质量单位,用于计量微小质量,其定义为 非束缚 且 静止的 碳-12 中性原子,处于 核基态 和电子基态下质量的 1 12 [1][2]。

道尔顿(Dalton)是生物化学、分子生物学等领域衡量分子质量的常用单位。 该单位以碳-12原子质量的1/12为基准定义,符号为Da、Dal或D,1道尔顿等于1.661×10⁻²⁴克。 John dalton, english meteorologist and chemist, a pioneer in the development of modern atomic theory His theory was notable for, among other things, positing that each element had its own kind of atom and that atoms of various elements vary in size and mass Learn more about dalton in this article. The theory of atomism, proposed by dalton in the early 19th century and derived from meteorological studies, is the foundation for our modern concept of the atom. 历史 亨利·道尔顿(Henry Dalton,1803-1884),出生于英格兰,1820年航行到 秘鲁的 利马,成为商人。 最终指挥了一小块商船。 到1841年,他已经成为加利福尼亚沿海贸易的杰出人物。 道尔顿(Dalton)于1845年被授予两个方联赛兰乔·旧金山(Rancho Rancho)。

Chemist john dalton is credited with pioneering modern atomic theory He was also the first to study color blindness. From his own experiments and observations, as well as the work of his peers, dalton proposed a new theory of the atom This later became known as dalton's atomic theory. Dalton is best known for his formulation of the atomic theory, which clarified our understanding of how atoms combine to form compounds, and how atoms may form new combinations during chemical reactions. 约翰·道尔顿(道耳顿) FRS (英语: John Dalton ,1766年9月6日—1844年7月27日), 化学家 、 物理学家 、 气象学家。 道尔顿是近代 原子理论 的提出者, 道尔顿分压定律 与 倍比定律 的发现者。 同时,他也是最早研究 色盲 的学者(其也是色盲患者)。

You may take it for granted that matter is made up of atoms, but what we consider common knowledge was unknown until relatively recently in human history

Most science historians credit john dalton, a british physicist, chemist, and meteorologist, with the development of modern atomic theory.
