Calcium crystallizes in a body-centered cubic structure at 467°C. (a) How many Ca atoms are contained in each unit cell?

Video transcript

Hi everyone. So in this question, we're asked to identify the number of chromium atoms and its unit cell. If it crystallizes with the body center even structured, recall that in a unit cell, the atoms have different contributions depending on their location. For the corner atoms, the contribution 18 Adams in the center, The contribution is one for the atoms in the face of a cube, The contribution is 1/ in a body center, cubic unit cell. For the corner Adams, we have eight, the atoms in the center. We have one. So for the number of atoms we get eight. Promise 18 last one. And this gives us two. Thanks for watching my video and I hope it was helpful.
