For the formation of covalent bond, the difference in the value of electronegativities should be
Equal to or less than 1.7
More than 1.7
1.7 or more
None of these
Covalent bond forms when electronegativity difference of two atom is equal to 1.7 or less than 1.7
For the formation of the covalent bond, the difference in the value of electronegativities should be equal to 1.7 or less than 1.7 .
When the difference in electronegativity of two elements in a compound is more than 1.7, what is the nature of the chemical bond?
The difference between the electronegativity value of fluorine and sodium is more than 1.7 so the compound formed by them will be ionic in nature.
