A propos du livre

Présentation de l'éditeur

The fonnulflB made use of in this work to describe compounds, are molecular formulsB; that is, they express the weight which, in the gaseous state, tiiey have, referred to H2, volume for volume, iniis is not the place to describe the methods by which the molecular volumes of volatile and nonvolatile bodies have been determined. The molecule we believe to be composed of atoms having the smallest proportion, by weight, of the element which can enter into combination. The atoms imite with one another to form molecules, in which their affinities are mutually satisfied: the measure of affinity is different for different atoms: the elements differ in quantivalency or atomicity. The measure of the atom of hydrogen, H, is selected as a basis; it is univalent, and is, as it were, a point of departure for other atoms. The metalloids are called univalent, bivalent, trivalent, jo., according as an atom is able to unite with, or replace, one, two or three atoms of hydrogen. The quantivalency of the metals depends upon the number of hydrogen atoms which the metal-atom can replace. Probably every atom has a fixed capacity for saturation a fixed chemical value.
