Like most metals it has a close-packed crystalline structure, and forms a ion in aqueous solution. The reason why, in a few cases, aluminium is referred to as a metalloid, from the article: It has some properties that are unusual for a metal; taken together, these are sometimes used as a basis to classify aluminium as a metalloid.
Another important property that many metal elements share is that they are malleable. This means that metals are relatively easy to be broken up into sheets. Also, most metals can be made into wire. This is what we know as being ductile. With the exception of potassium, lithium, and sodium, most metals have a high density.
13.04.2016· Say ‘calcium’ and a metallic substance does not immediately spring to mind, rather a chalky powdery rock or possibly a bottle of milk. Calcium is, however, a metal in its pure form, though rarely seen in this state due to its instability. In air, calcium decomposes rapidly into calcium hydroxide and calcium carbonate.
