Introduction to Inorganic Chemistry/Coordination Chemistry

Zn 4 O(BDC) 3, also called MOF-5, is a metal-organic framework in which 1,4-benzenedicarboxylate (BDC) anions bridge between ionic Zn 4 O clusters. The rigid framework contains large voids, represented by orange spheres. MOFs can be made from many different transition metal ions and bridging ligands, and are being developed for practical appliions in storing gases, especially H 2 …

The Difference Between Metals and Nonmetals

Jul 23, 2018· Most elements are metals. This includes the alkali metals, alkaline earth metals, transition metals, lanthanides, and actinides. On the periodic table, metals are separated from nonmetals by a zig-zag line stepping through carbon, phosphorus, selenium, iodine, and radon.These elements and those to the right of them are nonmetals.

Silver - Wikipedia

The metal is found in the Earth''s crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.

Metal - Wikipedia

Metals are present in nearly all aspects of modern life. Iron, a heavy metal, may be the most common as it accounts for 90% of all refined metals; aluminium, a light metal, is the next most commonly refined metal. Pure iron may be the cheapest metallic element of all at cost of about US$0.07 per gram.
