Question

using the above table of elements and the general trend of electronegativity discussed in class, order the following elements in order of most (5) electronegative to least (1) electronegative. as, f, w, pb, cl

Explanation:

Step1: Recall electronegativity trend

Electronegativity increases across a period and decreases down a group in the periodic table. Fluorine (F) is the most electronegative element.

Step2: Analyze given elements

Chlorine (Cl) is in the same group as F but below it, so it is less electronegative than F. Arsenic (As) is further to the left and down compared to Cl. Tungsten (W) is a metal and has relatively low electronegativity. Lead (Pb) is also a metal and is less electronegative than W in general trends.

Step3: Order the elements

F is the most electronegative (5), then Cl (4), As (3), W (2), and Pb (1).

Answer:

1. Pb
2. W
3. As
4. Cl
5. F
