Body Quote by Dmitri Mendeleev

Elements which are similar as regards their chemical properties have atomic weights which are either of nearly the same value (eg. Pt, Ir, Os)…

Certain characteristic properties of elements can be foretold from their atomic weights.

— Dmitri Mendeleev

Probably our atomic weights merely represent a mean value around which the actual atomic weights of the atoms vary within certain narrow limits... when…

Among nonclassical ions the ratio of conceptual difficulty to molecular weight reaches a maximum with the cyclopropylcarbinyl-cyclobutyl system.

— Paul Doughty Bartlett

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

— Dmitri Mendeleev

Moreover, the abundance of chemical compounds and their importance in daily life hindered the chemist from investigating the question, in what does the individuality…

The most common and most important result of them is that the nature and size of the effect on corresponding series of different elements…

But I must confess I am jealous of the term atom; for though it is very easy to talk of atoms, it is very…

— Michael Faraday

Experimental work of great refinement is necessary in order to determine atomic weights. No relationships between them have yet been certainly found which make…

Atoms have a nucleus, made of protons and neutrons bound together. Around this nucleus shells of electrons spin, and each shell is either full…

Atoms are very special: they like certain particular partners, certain particular directions, and so on. It is the job of physics to analyze why…
