Metals and Non- Metals Metals and non-metals are two distinct groups of elements with different physical and chemical properties. Understanding these characteristics is crucial for effectively utilizing various materials in our daily lives. by Crisca Engelbrecht Properties of Metals Metals have several unique properties that make them useful in various applications. Let's explore some of these properties: Properties of Metals Malleable Ductile Lustrous Dense Metals can be Metals can be drawn Metals have a shiny, Metals have high hammered or rolled into wires without reflective surface density, meaning they into thin sheets fracturing. when polished. have a lot of mass for without breaking. their volume. Magnetic Metals can attach themselves to a magnet. They are said to be attracted to a magnet. Interesting Facts About Metals 1 Mined from the Earth 2 Magnetic Properties Metals are naturally occurring Some metals, like iron, can be substances that are extracted from magnetized and used in various the Earth's crust through mining applications. processes. 3 Dense Materials Metals generally have a high density, making them heavy and durable. Properties of Non-Metals Flexible Brittle Dull Non-metals can be easily bent Non-metals are prone to Non-metals do not have a shiny, or shaped without breaking. cracking or shattering under reflective surface like metals. stress. Metals: Conductors of Electricity Metals have a high ability to conduct electricity, making them useful in electronic applications. Metals: Shiny Appearance Metals have a distinctive shiny, metallic look that sets them apart from non-metals. Non-Metals: Poor Conductors In contrast, non-metals are generally poor conductors of electricity and heat. Non-Metals: Range of Colors Non-metals can exhibit a diverse array of colors, from dull to vibrant, unlike the typically metallic appearance of metals. Importance of Understanding Metals and Non-Metals 1 Industrial Applications Metals and non-metals are used in various industries, such as construction, transportation, and electronics. 2 Environmental Impact Understanding the properties of metals and non-metals is crucial for responsible resource extraction and waste management. 3 Technological Advancements Ongoing research and development in materials science lead to new applications and improved technologies. Everyday Examples of Metals and Non- Metals Iron Glass Copper Rubber Used in construction A common non-metal Used in electrical A non-metal used in and tools. used in windows and wiring and plumbing. tires and other containers. products. Exploring the Diversity of Materials Metals 1 Diverse group with unique properties.
