Question

a solid has the Nacl structure.if the radius of cation is 120 pn. the maximum value of the radius of the anion is​

Answer 1

Answer:

for NaCl ratio of radius cation to anion is 0.5

so given radius of cation is 120pm

from that

( 120/radius of anion ) =0.5

radius of anion = 120÷0.5

radius of anion = 240pm

hope you understood mate!!
