I rather expect that we shall some day find, for what we now call atoms, a mathematico-mechanical explanation, which will render an account of atomic weight, of atomicity, and of numerous other properties of the so-called atoms. August Kekulé

The elements, if arranged according to their atomic weights, exhibit an apparent periodicity of properties. Dmitri Mendeleev

Instead of an attic with a few test tubes, bits of wire and odds and ends, the attack on the atomic nucleus has required the development and construction of great instruments on an engineering scale. Ernest Lawrence

The dropping of the Atomic Bomb is a very deep problem... Instead of commemorating Hiroshima we should celebrate... man's triumph over the problem [of transmutation], and not its first misuse by politicians and military authorities. Frederick Soddy

The elements which are the most widely diffused have small atomic weights. Dmitri Mendeleev

Whether a further development of the atomic hypothesis promises to advance our knowledge of the mechanism of chemical phenomena. August Kekulé

It may be difficult to follow up the idea in detail as we are not yet able to count the quantum packets in every case. For example, it may be that an atomic nucleus must be counted as a unique quantum. Georges Lemaître

Certain characteristic properties of elements can be foretold from their atomic weights. Dmitri Mendeleev
Certain characteristic properties of elements can be foretold from their atomic weights.
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
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.
Chemical homogeneity is no longer a guarantee that any supposed element is not a mixture of several of different atomic weights, or that any atomic weight is not merely a mean number. Frederick Soddy
Chemical homogeneity is no longer a guarantee that any supposed element is not a mixture of several of different atomic weights, or that any atomic weight is not merely a mean number.
We must expect the discovery of many as yet unknown elements-for example, elements analogous to aluminum and silicon- whose atomic weight would be between 65 and 75. Dmitri Mendeleev
We must expect the discovery of many as yet unknown elements-for example, elements analogous to aluminum and silicon- whose atomic weight would be between 65 and 75.
The atomic bombs will surely shorten the war, and let us hope that they will effectively end war as a possibility in human affairs. Ernest Lawrence
