The difference electronegativity values of sodium and bromine are; Sodium(Na) 0.9, Bromine(Br) 2.8 thus a difference of 1.9.
I will be considered as barely polar
The difference between a polar and non-polar molecule is in terms of sharing electrons. In the case of a polar molecule, electrons are not shared in an equal manner among the atoms that made the bond. But in the case of a non-polar molecule, electrons are shared in an equal manner among the atoms that made the bond.
Atoms with the lowest electronegativity values located on the leftmost part of the periodic table. The atom with the lowest electronegativity belongs to Francium.
You can only get the EN (electronegativity) of elements (not for molecules, such as CCl4). For molecules you want DIFFERENCE IN EN. Easiest way is to look up the values in the chart. C = 2.5 , Cl = 3.0 so difference is 0.5 General idea is that EN increases left to right in the chart and decreases top to bottom in the periodic table. F (4.0) being the highest and Fr(0.7) being lowest
This is the electronegativity of these atoms.
the difference between the electronegativity values of sodium and bromine is 1.9 , which is relatively high in general , high differences suggest ionic bonds.
2.03
Both Carbon and Sulphur have an electronegativity value of 2.5
An electronegativity difference of less that 1.7 between the atoms
I believe it is if the difference in electronegativity is > 1.
Both Carbon and Sulphur have an electronegativity value of 2.5
If the difference in the electronegativity between two atoms is more than 1.7, then the bond is ionic and if the difference is below 1.7, then the bond is covalent.

An electronegativity difference of less that 1.7 between the atoms
A covalent bond occurs when there is a large difference in electronegativity between two atoms for example. Fluorine is very electronegative (as it is a non metal) and Hydrogen is not as electronegative. in fact there is a large difference in the electronegativity values. Therefore, a covalent bond occurs.
