Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Main-Group Elements

Main-group elements, also known as representative elements, are found in groups 1, 2, and 13-18 of the periodic table. These elements typically exhibit a wide range of chemical properties and include metals, nonmetals, and metalloids. They are characterized by their valence electron configurations, which play a crucial role in determining their chemical behavior.

Periodic Table Groups

The periodic table is organized into vertical columns called groups, which categorize elements based on similar properties and electron configurations. Elements in the same group often exhibit similar reactivity and bonding characteristics. Understanding the group placement of an element helps predict its chemical behavior and interactions with other elements.

Transition Metals

Transition metals are found in groups 3 to 12 of the periodic table and are characterized by their ability to form variable oxidation states and complex ions. Manganese, specifically, is classified as a transition metal due to its position in group 7. This classification is important for understanding its chemical properties and its role in various chemical reactions.
