The Periodic Table (Basher book) different group of the periodic table (hydrogen, the alkali metals, the alkaline earth metals, the transition metals, the boron elements, the carbon elements, the nitrogen elements, the oxygen elements, the halogen elements, the noble gases, the lanthanides and actinides, and the transactinides). For every type of then known atom, Basher has created a "manga-esque" cartoon, and for many types of atoms, Dingle, a high-school chemistry teacher who also developed an award-winning chemistry website has written a couple paragraphs of facts to go with the cartoon. Dingle, who says that "[s]cience is a serious business", wanted in writing the book "to
History of the periodic table the Periodic Law for the chemical elements". He contributed the word 'periodic' in chemistry. The Russian chemist Dmitri Mendeleev was the first scientist to make a periodic table similar to the one used today. Mendeleev arranged the elements by atomic mass, corresponding to relative molar mass. It is sometimes said that he played 'chemical solitaire' on long train journeys, using cards with various facts about the known elements. On March 6, 1869, Mendeleev gave a formal presentation, "The Dependence Between the Properties of the Atomic Weights of the Elements", to the Russian Chemical Society. In 1869, the table was published
