In a paper on the atomic theory, published in 1826, he anticipated to a remarkable extent some ideas which are frequently supposed to belong to a later period ; and the continuation of these studies led him to the ideas about substitution ( metalepsis ) which were developed about 1839 into the theory ( Older Style Theory ) that in organic chemistry there are certain types which remain unchanged even when their hydrogen is replaced by an equivalent quantity of a halide element.

paper and atomic

Nevertheless, in spite of Rutherford's estimation that gold had a central charge of about 100 ( but was element Z = 79 on the periodic table ), a month after Rutherford's paper appeared, Antonius van den Broek first formally suggested that the central charge and number of electrons in an atom was exactly equal to its place in the periodic table ( also known as element number, atomic number, and symbolized Z ).
Although gold has an atomic number of 79, immediately after Rutherford's paper appeared in 1911 Antonius Van den Broek made the intuitive suggestion that atomic number is nuclear charge.

For the development of Command & Conquer 3: Tiberium Wars, Electronic Arts decided to radically alter its composition, and commissioned scientists from the Massachusetts Institute of Technology to provide a white paper describing the biophysics of Tiberium, its atomic structure, its method of transmutation, the form of the radiation that it emits, and the way to harness it for powering machinery and weapons — giving it the same treatment as would be suitable for a scientific journal article on a real substance.
