The real abhorrent consequence of the invention of atomic bombs is the fact that we still have them and they’re spreading. – Barry Commoner
Elements which are similar as regards their chemical properties have atomic weights which are either of nearly the same value (eg. Pt, Ir, Os) or which increase regularly (eg. K, Ru, Cs). – Dmitri Mendeleev
The elements, if arranged according to their atomic weights, exhibit an apparent periodicity of properties. – Dmitri Mendeleev
The structure of many cellular macromolecules has been revealed at the atomic level using x-ray crystallography. – Gunter Blobel
Information of fundamental importance to the general problem of atomic structure has resulted from systematic studies of the cosmic radiation carried out by the Wilson cloud-chamber method. – Carl D. Anderson
Certain characteristic properties of elements can be foretold from their atomic weights. – Dmitri Mendeleev
The magnitude of the atomic weight determines the character of the element, just as the magnitude of the molecule determines the character of a compound body. – Dmitri Mendeleev
My experiments proved that the radiation of uranium compounds can be measured with precision under determined conditions and that this radiation is an atomic property of the element of uranium. – Marie Curie
Thus at the beginning of 1906 it seemed to be established that the emitters of the spectral series of chemical elements are their positive atomic ions. – Johannes Stark
Elements and birthdays have been intertwined for me since boyhood, when I learned about atomic numbers. – Oliver Sacks
