The correct order of the chemical elements from highest to lowest electronegativity is: C. Br, Zn, Sc, Ca, K.
Electronegativity refers to a measure of the ability of an atom of a chemical element to attract any shared pair of electrons.
Generally, the electronegativity of a chemical element typically increases across the period from left to right.
In Chemistry, the electronegativity of some of the chemical element are:
Hence, the order of the chemical elements from highest to lowest electronegativity is:
1. Bromine (Br) = 2.96
2. Zinc (Zn) = 1.65
3. Scandium (Sc) = 1.36
4. Calcium (Ca) = 1.0
5. Potassium (k) = 0.82
