The multiple charges of transition metals can be further explained when examining concepts such as electronegativity, valence electrons, valence charge, oxidation number and electron configurations. The checkmarks in red represent the most common charge for the given transition metal. The most common charges for the first row of transition metals are provided as: Transition metals tend to have varying positive charges. The Transition Metals and Inner Transition Metals, of which are further divided into Lanthanides and Actinides are sometimes referred to as the Group B Elements. Notably exceptions are lead (Pb) and tin (Sn), which have charges of +2 and +4. Most main group elements possess one charge. We disregard talking about the ionic charges of metalloids because they share characteristics of both metals and non-metals.Įlements gain and lose electrons in order to be more like the noble gases and have the same number of electrons as them. Generally, metals lose electrons to become cations, while non-metals gain electrons to become anions. The Periodic Table (Major Group Classifications) The Periodic Table provides you with the element symbol, element number, the atomic mass and the atomic number. Recall that the elements of the periodic table are labeled as metals, non-metals, and metalloids. Major Classification Types of the Period Table The charges of the periodic table are important when determining the molecular formula for ionic compounds. Ionic compounds are composed of positive ion called a cation bonded to a negative ion called an anion. Periodic Table: Representative Elements & Transition Metals
