Above 882°C, titanium has a BCC crystal structure with a 5 0.332 nm. Below this temperature, titanium has an HCP structure with a 5 0.29503 nm and c 5 0.46831 nm. Determine the percent volume change when BCC titanium transforms to HCP titanium. Is this a contraction or expansion?

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
