Question

13. Cdo has NaCl structures with density 8.27 gem
If the ionic radius of 02- is 1.24 Å, determine
ionic radius of Cd2+ (moler mass of Cdo = 128
(1) 1.5 Å (2) 1.01 Å (3) 1.9 Å (4) 1.7 Å​

Answer 1

Answer:

3) 1.9 Å

Explanation:

beacuse, cdo of the structure with density 8.27÷×$(98)

thus, 1.9 is the answer.
