The bio-relevant metals (and derived compounds) of the Periodic Table of the Elements ( PTE ) are in the focus. The bulk elements sodium (Na), potassium (K), magnesium (Mg), and calcium (Ca) from the s -block, which are essential for all kingdoms of life, and some of their bio-...

The original table was created without a knowledge of the inner structure of atoms: if one orders the elements by atomic mass, and then plots certain other properties against atomic mass, one sees an undulation or periodicity to these properties as a function of atomic mass. The first to ...
Periodic table of elements with information on chemical elements like gold, silver, iron, neon, helium, chlorine, copper, cobalt, and more
Metals If you look at the periodic table, you will notice it is color coded. The colors represent elements that are metals, nonmetals, or metalloids. Examples of a metal, a nonmental, and a metalloid are illustrated in Figure 3. With the exception of mercury, all the metals are sol...

Dmitri Mendeleev First Table made by arranging the 63 known elements in order of atomic weight grouping them by similarity of properties. Predicted the existence of new elements pointed out that some of the known atomic weights were wrong He left space on his table for new elements, and predict...
Periodic table - Elements, Properties, Periodicity: The periodicity of properties of the elements is caused by the periodicity in electronic structure. The noble gases are chemically unreactive, or nearly so, because their electronic structures are stabl
