Which of the following unit cell having maximum number of atoms ?A. bc

1.	Which of the following unit cell having maximum number of atoms ?A. bccB. hcpC. fccD. cubic
Answer» Correct Answer - C In hcp - atoms in crystals are packed in ABAB pattern while in bcc - Number of atoms present `=8xx1/8+1=1+1=2` Number of atoms present in fcc `=8xx1/8+1/2xx6=1+3=4` therefore , fcc has highest number of atoms per unit cell
