Types of Bonds can be predicted by calculating the
difference in electronegativity.
If, Electronegativity difference is,
Less
than 0.4 then it is Non Polar Covalent
Between 0.4 and 1.7 then it is Polar Covalent
Greater than 1.7 then it is Ionic
For Na and Cl,
E.N of Chlorine = 3.16
E.N of Sodium = 0.93
________
E.N Difference 2.23 (Ionic Bond)
For C and O,
E.N of Oxygen = 3.44
E.N of Carbon = 2.55
________
E.N Difference 0.89 (Polar Covalent Bond)
For N and Cl,
E.N of Chlorine = 3.16
E.N of Notrogen = 3.04
________
E.N Difference 0.12 (Non-Polar Covalent Bond)
For B and O,
E.N of Oxygen = 3.44
E.N of Boron = 2.04
________
E.N Difference 1.40 (Polar Covalent Bond)
C wave transfer energy, but not matter this because waves transfer energy from one place to the other without moving matter:) hope this helps!
You can acquire the atomic mass of any chemical element by using the periodic table. I've provided an example on a document below to help you identify the components of an <em>element </em>block from the periodic table. Now if you want to find the mass of an exact amount of a substance you use moles for that. That's why it's called molar mass. To find the molar mass of a substance follow this little guide:
- Start with the number of grams of each element given.
- Convert the mass of each element to moles utilizing the molar mass from the periodic table.
- Divide each mole value by the smallest number of moles deciphered.
- Round your answer. This is the mole ratio of the element.
