Q. Which element is most electronegative among Arsenic, Nitrogen and Phosphorus? Answer:
Nitrogen
Notes: Electronegativity is a measure of the ability of an atom to attract the electrons when the atom is part of a compound. Since metals have few valence electrons, they tend to increase their stability by losing electrons to become cations. Consequently, the electronegativities of metals are generally low. Electronegativity of following elements is:
