Which element is most electronegative among Arsenic, Nitrogen and Phos...
- Nitrogen is the most electronegative among Arsenic, Nitrogen and Phosphorus.
- As per the periodic table, Nitrogen has an atomic number of 7 and hence its electron configuration is 1s2 2s2 2p3.
- Amongst all the others nitrogen has the highest tendency to attract a shared pair of electrons towards itself.

Which element is most electronegative among Arsenic, Nitrogen and Phos...
Electronegativity
Electronegativity is a measure of the tendency of an atom to attract a shared pair of electrons towards itself when it is participating in a chemical bond. It depends on several factors, including the number of protons in the nucleus and the distance between the nucleus and the outermost electrons.
Arsenic (As)
Arsenic is a chemical element with the symbol As and atomic number 33. It is a metalloid and belongs to the nitrogen group on the periodic table. Arsenic has five valence electrons in its outermost shell.
Nitrogen (N)
Nitrogen is a chemical element with the symbol N and atomic number 7. It is a nonmetal and belongs to the pnictogen group on the periodic table. Nitrogen has five valence electrons in its outermost shell.
Phosphorus (P)
Phosphorus is a chemical element with the symbol P and atomic number 15. It is a nonmetal and belongs to the pnictogen group on the periodic table. Phosphorus has five valence electrons in its outermost shell.
Electronegativity Trend
The electronegativity of an element generally increases as you move across a period from left to right on the periodic table. This is because the number of protons in the nucleus increases, leading to a stronger attraction for electrons.
Comparing Electronegativity
Among arsenic, nitrogen, and phosphorus, nitrogen is the most electronegative element. This is because nitrogen has a smaller atomic radius compared to arsenic and phosphorus. As you move across a period, the atomic radius decreases due to the increasing positive charge in the nucleus. As a result, the outermost electrons in nitrogen are closer to the nucleus, leading to a stronger attraction and higher electronegativity.
Phosphorus and arsenic have larger atomic radii than nitrogen, which means their outermost electrons are farther from the nucleus. As a result, the attraction for electrons is weaker, and their electronegativities are lower compared to nitrogen.
Therefore, the correct answer is option 'A', nitrogen is the most electronegative element among arsenic, nitrogen, and phosphorus.
