Select Page The Charts In the Russian chemist Dmitri Mendeleev developed the first version of the now very familiar table of chemical elements. This showed all the elements that were known at that time and some that were discovered later. The elements are shown in order of increasing number of protons in the nucleus , starting with Hydrogen H which has one proton. The rows and columns are also arranged to highlight families of elements with similar chemical properties, including for example their propensity to interact, or not, with other elements. Thus the position of an element in the periodic table tells you a lot about how that element is made and how it behaves. The same is true of the Sound Foundations chart.
