How to Find the Ionic Charge for an Element. When you are working with ionic compounds (they are called ionic because they consist of ions) you'll often need to determine the ionic charge.This is especially the case when you are writing formulas based on the chemical name.

Calculate the charges of polyatomic ions, or molecules with positive or negative charges, by looking at their oxidation numbers. The hydroxide ion, for example, has a -1 charge. Oxygen generally has an oxidation number of -2, while hydrogen has +1. The charge of the hydroxide ion is negative because (-2)+ (+1) = -1.

A metal reacts with a nonmetal to form an ionic bond. You can often determine the charge an ion normally has by the element’s position on the periodic table: The alkali metals (the IA elements) lose a single electron to form a cation with a 1+ charge. The alkaline earth metals (IIA elements) lose two electrons to form a 2+ cation.

Finding ionic charges for elements on the Periodic Table is a fundamental skill in chemistry. There are two primary methods to help you remember the charges. The first method is to consider the ...

An easy way to work out the charge of an atom is to look at the periodic table. Elements on the left side of the table usually become positively charged ions and elements on the right side of the table typically have a negative charge. However, you can use a scientific formula to determine the formal charge of an atom.

Ions in chemistry can be a single charged atom, or they can be a group of atoms that act as an ion. These groups of atoms are called polyatomic ions. Polyatomic ions each carry a specific charge, which is determined by their numbers of valence electrons. Many chemistry classes require students to know at least some of the basic polyatomic ions.

The electric charge on a transition metal ion is all about the number of electrons it has lost to other atoms in a chemical reaction. To determine the charge on a given transition metal atom, you have to consider what element it is, the charges on the other atoms in the molecule, and the net charge on the molecule itself.
