Identify each of the following elements as a metal, a nonmetal, or a metalloid: a. located in Group 2A (2)

Verified step by step guidance

1. Identify the location of Group 2A (2) on the periodic table. Group 2A is also known as the alkaline earth metals.
2. Recall that elements in Group 2A are metals. These elements include beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
3. Understand that metals are typically characterized by their ability to conduct electricity, their malleability, and their tendency to lose electrons during chemical reactions.
4. Conclude that any element located in Group 2A (2) is classified as a metal.
5. Summarize that the element in question, being in Group 2A, is a metal.

Key Concepts

Periodic Table Groups

The periodic table is organized into columns called groups, which categorize elements based on similar chemical properties. Group 2A, also known as Group 2, contains alkaline earth metals, which are characterized by having two electrons in their outermost shell. Understanding the properties of elements in this group is essential for identifying their classification as metals.

Metal Characteristics

Metals are typically characterized by their ability to conduct electricity and heat, malleability, ductility, and a shiny appearance. They tend to lose electrons during chemical reactions, forming positive ions. Elements in Group 2A are metals, specifically alkaline earth metals, which exhibit these properties and are reactive, especially with water.

Element Classification

Elements are classified into three main categories: metals, nonmetals, and metalloids. Metals are generally found on the left side and in the center of the periodic table, while nonmetals are located on the right. Metalloids possess properties of both metals and nonmetals and are found along the zig-zag line. Recognizing these classifications helps in understanding the behavior and reactivity of elements.
