Calcium is a crystalline solid. The Alkaline Earth Metals have been tested many times but the only crystalline solid is Calcium.
as with all metals, lead is a polycrystalline solid.
No. Mercury is a metal that is liquid at room temperature.
Metals are crystalline because the bond via metallic bonding, are unrestricted as to number and position of nearest neighbor atoms, and have dense atomic packing. Due to these traits, they form a lattice microstructure (i.e., crystal)
Silicon is a solid at room temperature. It is a metalloid with a crystalline structure that exhibits properties of both metals and non-metals.
All metals have a crystalline structure.
