How to determine the charge of an ion?​

To determine the charge of an ion, you need to consider the number of protons and electrons in the ion. Here's how you can determine the charge of an ion:
Identify the element: Determine which element the ion represents.
1. Determine the atomic number: Find the atomic number of the element, which represents the number of protons in the nucleus.

2. Determine the electron configuration: Determine the electron configuration of the neutral atom. This will tell you the number of electrons in the neutral state.

3. Compare electrons to protons: Compare the number of electrons to the number of protons in the neutral atom. If the number of electrons is equal to the number of protons, the atom is neutral (no charge).

4. Determine the ion's charge: If there is a difference between the number of electrons and protons, the atom has gained or lost electrons, resulting in an ion with a positive or negative charge, respectively.
