Platinum table of elements
WebbPlatinum is a chemical element with the atomic number 78 in the periodic table. It’s an extremely rare metal with an abundance in Earth’s crust of about a millionth of 1 percent. Known since ancient times, this transition metal has strong anti-corrosive properties and makes for an excellent conductor of electricity. WebbThe atomic radius of a chemical element is the distance from the center of the nucleus to the outermost shell of an electron. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Depending on the definition, the term may apply only to isolated atoms, or also to atoms in condensed matter, …
