All elements belong to same column as fluorine, are non-metals and are highly electronegative in character. All of them have valence electrons equal to seven, and thus can accept one electron to complete their octet.

Boron is metalloid while all other elements in the same column of the Periodic Table are metals, thus metallic character is common in the same column of the periodic table as boron have.

Nitrogen (7): 2, 5 Phosphorus (15): 2, 8, 5 Since, electronegativity decreases with moving from top to bottom in a group, thus Nitrogen will be more electronegative.

Nitrogen (atomic number 7) and phosphorus (atomic number 15) belong to group 15 of the Periodic Table. Write the electronic configuration of these two elements. Which of these will be more electronegative? Why?
Nitrogen (7): 2, 5 Phosphorus (15): 2, 8, 5 Since, electronegativity decreases with moving from top to bottom in a group, thus Nitrogen will be more electronegative.
