Welcome to our comprehensive guide on the Atomic Charge Calculator. This article will help you understand the concept of atomic charge, the formula behind it, and its applications. We will also provide detailed explanations on how the calculator works and address frequently asked questions.

Atomic Charge

Atomic charge refers to the net charge of an atom, which is the difference between the number of protons and electrons present in the atom. This charge determines the atom’s electrical properties and its ability to form bonds with other atoms.

Atomic Charge Formula

Understanding the formula

The formula for calculating atomic charge is quite simple:

AC = P – E


  • AC is the Atomic Charge (eV)
  • P is the number of protons
  • E is the number of electrons

To calculate the atomic charge, subtract the number of electrons from the number of protons.

Example calculation

Let’s walk through an example calculation to better understand the formula:

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)
