Which of the following gives the correct increasing order of the atomic radii of O, F and N?
- Electropositive nature of the element(s) increases down the group and decreases across the period
- Electronegativity of the element decreases down the group and increases across the period
- Atomic size increases down the group and decreases across a period (left to right)
