WebJun 8, 2024 · Most metals and alloys crystallize in one of three very common structures: body-centered cubic (bcc), hexagonal close packed (hcp), or cubic close packed (ccp, also called face centered cubic, fcc). In all three structures the coordination number of the metal atoms (i.e., the number of equidistant nearest neighbors) is rather high: 8 for bcc ... Webcovalent bond: A type of chemical bond where two atoms are connected to each other by the sharing of two or more electrons. diamond: a glimmering glass-like mineral that is an allotrope of carbon, in which each carbon atom is bonded to four others with a tetrahedral geometry. carbide: A compound composed of carbon and a less electronegative ...
