If `R` is the radius of the octahedral voids and `r` is the radius of the atom in close packing, then `r//R` is equal to

A

`2.41`

B

`4.76`

C

`3.22`

D

`9.1`

Text Solution

Verified by Experts

The correct Answer is:
A
For `OV`,
`R/r` (i.e., `(r_(o+))/(r_(ɵ))` or `(r_("void"))/(r_(ɵ))`) `= 0.414`
`:. (r)/(R) = (1)/(0.414) = 2.41`
