Question

Q1. Metallic vanadium crystallizes in a body-centered cubic lattice, with one V atom per lattice point. If the edge length of the unit cell is found to be 301 pm, what is the metallic radius of V in pm? pm

Q2. Metallic aluminum crystallizes in a face-centered cubic lattice, with one Al atom per lattice point. If the metallic radius of Al is 143 pm, what is the volume of the unit cell in pm³ and in cm³?

Q3. The substance alpha chromium is found to crystallize in a cubic lattice, with an edge length of 871.7 pm. If the density of solid alpha chromium is 7.561 g/cm³, how many Cr atoms are there per unit cell?

Your answer should be an integer: atoms
