Periodic table of elements

The elements are organised according to their increasing atomic mass and similar chemical properties.

Pyrocollodion

mixture of nitrocullulose and ether, powdery and smokeless use to identify the characteristiv spectra of different elements

Gas pycnometer

graduated flask for measuring the precise density of a gas

Prediction of elements : eka-bore, exa-aluminium and eka-silicium

PERIODIC TABLE

However,

Finally,

Henry Moseley developed a new form to the periodic table, which is now in every school's or science's books.

After almost one century of research to classification from Lavoisier, Dalton to Dumas and many others, it is Dmitri Ivanovich Mendeleev who is today know as the father of the periodic of elements.
