Chromium crystallizes with a body-centered cubic unit cell. The radius of a chromium atom is 125 pm. Calculate the density of solid crystalline chromium in grams per cubic centimeter.
Added by Adam B.
Step 1
In a body-centered cubic unit cell, the atoms at the corners and the center of the cell touch along the body diagonal. The body diagonal is equal to 4 times the atomic radius (r). So, we can write: Body diagonal = 4r => 4*125 pm = 500 pm The body diagonal of a Show more…
