You are given a small bar of an unknown metal X. You find the density of the metal to be 10.5 g/ cm3. An X-ray diffraction experiment measures the edge of the face-centered cubic unit cell as 4.09 Å (1 Å = 10–10 m). Identify X.
Answer to relevant QuestionsTitanium metal has a body-centered cubic unit cell. The density of titanium is 4.50 g/cm3. Calculate the edge length of the unit cell and a value for the atomic radius of titanium. (Hint: In a body-centered arrangement of ...Rationalize why chalk (calcium carbonate) has a higher melting point than motor oil (large compounds made from carbon and hydrogen), which has a higher melting point than water, which engages in relatively strong ...The structures of some common crystalline substances follow. Show that the net composition of each unit cell corresponds to the correct formula of each substance. The unit cell of MgO is shown below. Does MgO have a structure like that of NaCl or ZnS? If the density of MgO is 3.58 g/cm3, estimate the radius (in centimeters) of the O2- anions and the Mg2+ cations. Perovskite is a mineral containing calcium, titanium, and oxygen. The following diagrams represent the unit cell. a. What is the formula of perovskite? b. An alternative way of drawing the unit cell of perovskite has calcium ...
