Chemical groups in The Periodic table
Alkali Metals 2 Alkaline earth metals 2 Lanthanides 1, 2 Aktinides 1, 2 Transition Elements 2
Metals 2 Metalloids Nonmetals Halogens 3 Noble gases 3

1 Actinides and Lanthanides are Inner transition elements.

2 Alkali metals, Alkaline earth metals, Transition elements, Actinides, Lanthanides and metals are known as metals.

3 Halogens and noble gases are too nonmetals.

  • elements with black color proton number are gases.
  • elemnets with blue color proton number are liguids.
  • elements with white color proton number are solids

Borders show natural occurrence

elements with full border lines have isotopes older than earth (primordial)

elements with cut boarder lines arised naturally by elementary particle decay and they are not older than earth

elements with dot borders lines were create artificially (synthetic elements)

elements without border lines haven´t discover yet.

Dmitri Mendeleev, also spelt Dmitry Mendeleyev, middle name (patronymic) Ivanovich, a Siberian-born Russian chemist, was the first scientist to make a periodic table much like the one we use today. Mendeleev arranged the elements in a table ordered by atomic mass. It is sometimes said that he played "chemical solitaire" on long train rides using cards with various facts of known elements.[8] On March 6, 1869, a formal presentation was made to the Russian Chemical Society, entitled The Dependence Between the Properties of the Atomic Weights of the Elements.

Mendeleev predicted the discovery of other elements and left space for these new elements, namely eka-silicon (germanium), eka-aluminium (gallium), and eka-boron (scandium). Thus, there was no disturbance in the periodic table.

He pointed out that some of the then current atomic weights were incorrect.

He provided for variance from atomic weight order

Unknown to Mendeleev, Lothar Meyer was also working on a periodic table. In his work published in 1864, Meyer presented only 28 elements, classified not by atomic weight but by valence alone. Also, Meyer never came to the idea of predicting new elements and correcting atomic weights. Only a few months after Mendeleev published his periodic table of all known elements (and predicted several new elements to complete the table, plus some corrected atomic weights), Meyer published a virtually identical table. Some people consider Meyer and Mendeleev the cocreators of the periodic table, although most agree that Mendeleev´s accurate prediction of the qualities of the undiscovered elements lands him the larger share of credit. In any case, at the time Mendeleev´s predictions greatly impressed his contemporaries and were eventually found to be correct. An English chemist, William Odling, also drew up a table that is remarkably similar to that of Mendeleev in 1864.
