Answer
We will start with highest electronegativity element and end with low.
1. Fluorine (F) - 3.98
2. Oxygen (0) - 3.44
3. Nitrogen (N) - 3.04
4. Carbon (C) - 2.55
5. Boron (B) - 2.04
6. Sodium (Na) - 0.93
Step-by-step explanation
Moving from left to right of the periodic table, electronegativities increases whereas when moving from top to bottom, the electronegativity decreases.
