Naming and Charges of Ions

This lesson covers the naming of monoatomic ions using the periodic table. It explains the difference between positively and negatively charged ions, detailing how to name them based on their group in the periodic table. Positively charged ions from groups 1A to 3A have a single charge, while those from group B can have multiple charges, indicated by Roman numerals. Negatively charged ions require changing the element's ending to 'ide'. The lesson includes examples and exceptions to these rules.
