`A1`through the electronegativity scale is somewhat arbitrary we can use it with resonable confidence to make predictions about

Options

A. chemical bonding
B. ionization enthalpy
C. electron gain enthalpy
D. none of these.

Answer

A

Explanation

`Delta_(i)H` and `Delta_(eg)H` are precise quantitative concepts. However, the qualitative concept of electronegativity is more useful in describing chemical bonding : Two elements with quite differnet electronegativity (a metal and a nonmetal) tendt to react with each other to form ionic compounds. The less eletronnegative element gives up its eloectron `(s)` to the more electronegative element. two nonmetals with similar electronegativies tend to form cavalent. In this sharing, the more electronegativity element attains a greater share.
