Aluminium crystallizes in FCC structure....

Aluminium crystallizes in FCC structure. Atomic radius of the metalics 125 pm. Calculate the edge length of the unit cell. (Multiply the answer with 10)

Text Solution

Verified by Experts

The correct Answer is:
3533
In a face centred cubic structure, radius (r), is related to length of the side (a) as :
`" "r = a/(2sqrt(2))`
or `" " a = 2sqrt(2)`
`" " r = 125 p m`
`:. " " a = 2 xx 125 xx 1.414`
`" " = 353.3 nm.`
