A sample of an alkali metal that has a BCC unit cell is found to have a mass of 1.000 g and a volume of 1.0298 cm³. When the metal reacts with excess water, the reaction produces 539.29 mL of hydrogen gas at 0.980 atm and 23°C. Identify the metal, determine the unit cell dimensions, and give the approximate size of the atom in nanometers.
