Interaction of Elements with Hydrogen and with Each Other

The periodic system of chemical elements of Mendeleyev is supplemented with data, which allow using it as an encyclopedic reference book. In addition to the information usually present in such tables, information is provided on the hydrogen compounds formed by each element. In addition, it allows you to quickly find the answer to the question with which chemical element the chemical element under investigation interacts and how. Each cell in this table contains a large amount of information obtained from the analysis of many reference books and monographs. The table will be useful not only for scientists working with hydrogen, but for all materials of scientists, chemists and physicists.
