The article gives examples of trends in properties of the elements, their ions, and their compounds, which can usefully be examined from the perspective of the periodic table as a whole, rather than by looking at one group of elements (or even individual elements) at a time. The properties...

The periodic table of elements, simply known as the periodic table, is a two-dimensional chart of the chemical elements. The elements are organized by atomic number, electron configuration, and other periodic patterns based on the elements’ chemical properties....
The "block" nomenclature of the periodic tablerefers to the sub-orbital type (quantum numberℓ, ors-p-d-fclassification) of the highest-energy orbitals that are occupied in a given element. Notice that: Forn=1 there is nopblock, and thesblock is split so that helium is placed in the...
Germanium, with the chemical abbreviationGe, is a chemical element having the atomic number 32 and belonging to period 4 of the periodic table of elements. It is a hard, brittle, silvery-white semimetal that is a member of thecarbon group. Its physical properties are similar to those ofsilic...
