Atomic Charge Formula
The following formula is used to calculate the Atomic Charge.
AC = P – E
- Where AC is the Atomic Charge (eV)
- P is the number of protons
- E is the number of electrons
How to Calculate Atomic Charge?
The following two example problems outline how to calculate the Atomic Charge.
Example Problem #1:
- First, determine the number of protons. In this example, the number of protons is given as 50.
- Next, determine the number of electrons. For this problem, the number of electrons is given as 49.
- Finally, calculate the Atomic Charge using the equation above:
AC = P – E
Inserting the values from above and solving the equation:
AC = 50 – 49 = 1 (eV)
Example Problem #2:
Using the same process as above, first define the variables required by the formula. In this case, these values are provided as the following:
number of protons = 15
number of electrons = 17
Entering these values gives:
AC = 15 – 17 = -2 (eV)
