#ExplanationElectronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used electronegativity scale, and it ranges from 0.7 (francium) to 4.0 (fluorine).The electronegativity of an element can be affected by both its atomic number and the distance that its valence electrons reside from the charged nucleus. The higher the associated electronegativity number, the more an element attracts electrons.In general, electronegativity decreases as we move down a group (column) in the periodic table. This is because as we move down a group, the number of energy levels (shells) increases, which means the valence electrons are further away from the nucleus and are therefore less attracted to it.In this case, Nitrogen (N), Arsenic (As), and Bismuth (Bi) all belong to Group 15 (VA) of the periodic table. Nitrogen is at the top of the group, while Arsenic is in the middle and Bismuth is at the bottom.According to the Pauling scale, the electronegativities of these elements are as follows:- Nitrogen (N): 3.04- Arsenic (As): 2.18- Bismuth (Bi): 2.02#AnswerGiven the above electronegativities, the elements ranked from highest to lowest electronegativity are:1. Nitrogen (N)2. Arsenic (As)3. Bismuth (Bi)
