The coordination number of BCC, SCC and FCC are:
The correct order of the packing efficiency in different types of nuit cells is ............
(a) fcc < bcc < simple cubic (b) fcc > bcc > simple cubic
(c) fcc < bcc > simple cubic (d) fcc < bcc > simple cubic
A metal crystallizes into two cubic phases, FCC and BCC whose unit cell lengths are 3.5 and 3.0 Å respectively. The ratio of densities of FCC and BCC.
