Question:
Choose the correct order of atomic radii of fluorine and neon (in pm) out of the options given below and justify your answer.
(i) 72, 160
(ii) 160, 160
(iii) 72, 72
(iv) 160, 72
Solution:
(i) 72, 160
Because neon has van der Waals radii and fluorine has covalent radii. Covalent radius is always less than van der Waal’s radius, so the radius of Fluorine is 72pm and Neon is 160pm.
