you subtract the largest EN from the smallest and then look @ the number
if its...
0-0.5 its Pure covalent
0.5-1.7- Polar covalent
1.7-3.3 its Ionic bond
good luck :)
lol idk a word ur sayin
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
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
To calculate the anticipated pH you need to have a balanced equation of your reaction, use the appropriate Ka or Kb values and determine the anticipated amount of excess ions and whether they are H+ or OH-. These will determine your pH.
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.
The difference electronegativity values of sodium and bromine are; Sodium(Na) 0.9, Bromine(Br) 2.8 thus a difference of 1.9.
the difference between the electronegativity values of sodium and bromine is 1.9 , which is relatively high in general , high differences suggest ionic bonds.
Both Carbon and Sulphur have an electronegativity value of 2.5
2.03
An electronegativity difference of less that 1.7 between the atoms
In a bond if the electronegativity is stonger in an atom then it gains a negative charge and the atom with the weaker electronegativity gains a posotive charge.
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.
I will be considered as barely polar
