Type of Substance as a New Physical Quantity

The International System of Units (SI) is founded on 7 base units (meter, kilogram, second, ampere, kelvin, mole, candela) for 7 base quantities (lenght, mass, time, electric current, thermodynamic temperature, amount of substance, luminous intensity) assumed to be mutually independent. There is a need for a new quantity that describes the quality of type of the substance. The processing and introduction of this quantity is investigated. The method of the maximum possible atomic number of elements in Mendeleev's Periodic Table was used. Here is a proposal of the 8th base quantity called type of substance and its unit Boscovich, B. This quantity cannot be derived from 7 existing quantities and therfore should be introduced as a separete new one. It is also explained why the unit boscovich for type of substance is suggested.
