Question

What is the correct order of these items from smallest to largest radius? Group of answer choices

Na+ < F- < O2-
Na+ < O2- <  F-
O2- < F- < Na+
O2- < Na+ < F-​

Answer 1

I'm assuming you're talking about atomic radius. It'd be the 2nd.

Fluoride has the smallest (group 17)

Oxygen has the 2nd smallest (group 16)

Sodium has the largest (group 1)

Sorry it took so long, didn't know it was multiple choice :)
