Calculation of the electronegativity of fluorine from thermochemical data
1. 
 
A method for calculating electronegativities from a combination of data on bond energies has been proposed. 
 
 
 
 
2. 
 
The electronegativity of fluorine is less than the generally assumed value, to wit, xF=3.5 instead of 4.0 on the Pauling scale.
