Do you expect us to dig for the data?

#### Explanation:

For the sequence $N , O , F$ $Z$, the atomic number increases from $7$ to $8$ to $9$....And because the nuclear charge increases, and the shielding offered by the valence electrons is INEFFECTIVE for a partially vacant shell, the atomic radius becomes smaller....and you must quote these data...
