Prout's hypothesis

固有名詞

歴史的

(historical, chemistry) An early 19th-century attempt to explain the existence of the various chemical elements: the hypothesis that, since the atomic weights for known elements appeared to be whole multiples of the atomic weight of hydrogen, the hydrogen atom was the only truly fundamental object, and the atoms of other elements were actually groupings of various numbers of hydrogen atoms.

日本語の意味

19世紀初頭の化学における仮説。既知の化学元素の原子量が水素原子の原子量の整数倍であることに着目し、水素原子を基本単位とみなし、他の元素は複数の水素原子が集まったものだとする説。

Prout's hypothesis, proposed in the early 19th century, suggested that atoms of all chemical elements were simple multiples of hydrogen atoms, but more precise measurements later disproved it.

プラウトの仮説は19世紀初頭に提唱され、すべての化学元素の原子が水素原子の単純な複数倍であるとする考えだったが、より精密な測定によって後に否定された。
