But during this epoch remains any hypothesis

But during this epoch remains any hypothesis. III. Effects of the quantitative chemical analysis yield strong observational datum to the atomic doctrine. It becomes necessary for an explanation of the law of multiple proportions of the Dalton. Revertively, on the basis of this law the relative masses of atoms of different devices (combining weights) are spotted. The got stronger representation about serves as the basic guess of the mechanical theory of heat and the theory of gases. Representation about a molecula as to certain bunch, is found out by the bound chemical forces. Mendeleyev’s periodic law positions close relationship of various views IV. Studying of transit of an electricity through gases, discovering of a radio-activity and other facts was found out by variability, divisibility. And, hence, complexity of a constitution chemical On the other hand, charged helium («-particles) and the electrons which are taking off from radioactive devices, possess so major velocities and, hence, energy that it is possible to find activity of everyone separately, on phosphorescence flashouts (), on electrical and photographic activities. Thanks to it, the path of each prompt charged can become visible personally. , the substance discontinuity becomes obvious. The discontinuity device is found further in laws of interaction of particles of substance and in radiance (the theory of quanta). Application of the theory of quanta to atomic spectrums allows to learn interior Thus, from a philosophical guess the atom becomes gradually at first a verisimilar hypothesis, then a hypothesis imminent and, at last, a doubtless reality.
