In which type of viods magnesium and silicon is present respectively in asbestos `(Mg_(3)Si_(2)O_(5))` if `r_(Mg^(2+))//r_(O^(2)) = 0.59` and `(r_(Si^(4+)))/(r_(O^(2-))) = 0.29`

A

tetrahedral & octahedral

B

Both tetrahedral

C

octahedral & tetrahedral

D

both octahedral

Text Solution

Verified by Experts

The correct Answer is:
C
`(r^(+))/(r^(-))=0.414 - 0.732`, Co. No. 4 and 6
`(r^(+))/(r^(-))=0.225-0.414`, Co. No - 4
Hence, (C ) is the correct answer.
