Put the elements in order from the highest electronegativity at the top of yourlist, to the lowest at the bottom,Fluorine (F)Boron (B)Nitrogen (N)1 Carbon (C)1. Sodium (Na)t Oxygen (0)

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
Explanation
Moving from left to right of the periodic table, electronegativities increases whereas when moving from top to bottom, the electronegativity decreases.
