Nitrogen and phosphorus belong to the group 15 of the periodic table. Which of these will be more electronegative?a)Phosphorusb)Both are equally electronegativec)Nitrogend)None of theseCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

Nitrogen (atomic number 7) and phosphorus (atomic number 15) belong to group 15 of the Periodic Table. 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.

Answer

Phosphorus electron configuration is 1s2,2s2,2p6,3s2,3p3, nitrogen has 1s2,2s2,2p3; the electronegativity is a property of valence electrons (energy it takes to remove the electron) in nitrogen it is second shell (2s2,2p3) while in phosphorus it is the third shell (3s2,3p3), more remote from the nucleus and therefore easier to remove.Therefore Nitrogen is more electronegative than Phosporous.

Answer

Nitrogen is more electronegative than phosphorus. On moving down a group, the number of shell increases. Therefore, the valence electrons move away from the nucleus and the effective nuclear charge decreases.

Answer

Electronegativity of Nitrogen and Phosphorus
Nitrogen and phosphorus both belong to group 15 of the periodic table, which is also known as the nitrogen group. When comparing the electronegativity of these two elements, it is important to consider their positions in the periodic table.

Electronegativity Definition
Electronegativity is the tendency of an atom to attract a shared pair of electrons towards itself in a covalent bond. It is a measure of an atom's ability to attract and hold onto electrons.

Nitrogen Electronegativity
Nitrogen has an electronegativity value of 3.04 on the Pauling scale. This high electronegativity value indicates that nitrogen has a strong tendency to attract electrons towards itself in a chemical bond.

Phosphorus Electronegativity
Phosphorus has an electronegativity value of 2.19 on the Pauling scale. This value is lower than that of nitrogen, indicating that phosphorus is less electronegative than nitrogen.

Conclusion
In conclusion, nitrogen is more electronegative than phosphorus. This means that nitrogen has a stronger tendency to attract electrons towards itself compared to phosphorus. The electronegativity values of these elements play a significant role in determining their chemical properties and reactivity in various compounds.
