Mendeleev (1834–1907) was based on the phenomelogical regularity of the chemical/physical properties exhibited by sixty-six elements known at the time, ordered in function of their atomic weights (Mendeleev 1869 ).

The atomic number of each element increases by one, reading from left to right. Block Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f).
WebbThe periodic table is made up of elements but these can combine with other elements to form compounds. Sometimes they are found together but they do not have a bond between them so we call them a mixture. Lets explore these meanings now looking at some examples.
