Identify the group 3A element that best fits each of the following descriptions.
(a) Is the most abundant element of the group

Key Concepts

Group 3A Elements

Group 3A (or Group 13) of the periodic table includes elements such as boron, aluminum, gallium, indium, and thallium. These elements share similar properties, including their tendency to form +3 oxidation states. Understanding the characteristics and trends of these elements is essential for identifying which one is the most abundant.

Abundance of Elements

Elemental abundance refers to the relative quantity of an element found in the Earth's crust or in the universe. For Group 3A, aluminum is the most abundant element, making up about 8% of the Earth's solid surface. Recognizing the significance of abundance helps in determining which element fits the description provided.

Periodic Trends

Periodic trends are patterns observed in the properties of elements across the periodic table, including atomic size, electronegativity, and ionization energy. These trends can influence the behavior and reactivity of elements in Group 3A. Understanding these trends aids in predicting which element is most likely to be abundant based on its position in the periodic table.
