Development of the chemical bonding theory
WebHe proposed that elements are composed of indestructible atoms, that each atom of an element is identical, that atoms of different elements differ in terms of mass, and that compounds consist of characteristic groupings of atoms. Because a compound is characterized by the grouping of atoms and each atom has a characteristic mass, it was … WebThe two theories are similar in that both assume that • bonds occur due the sharing of electrons between atoms; • the attraction of bonding electrons to the nuclei of the …
