Question

14. a) Name the scientist introduced electronegativity scale. b) Which is the element with highest electronegativity value? Write the value. c) Which is the element with the lowest electronegativity value?​

Answer 1

Answer:

a). Skoltech chemists have proposed a new electronegativity scale and published their findings in Nature Communications. The concept of electronegativity introduced by Linus Pauling, a great American chemist, in the 1930s refers to the ability of an atom to attract electron density.

b). fluorine

Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element, while francium is one of the least electronegative.

c). cesium

Of the main group elements, fluorine has the highest electronegativity (EN = 4.0) and cesium the lowest (EN = 0.79).
