how are metals, non-metals, and metalloids organised in the periodic table
Metals, non-metals, and metalloids are organised in the periodic table based on their physical and chemical properties.
Metals are found on the left side and in the middle of the periodic table, and they are highly conductive, malleable, and ductile. They tend to have a shiny appearance and are solids at room temperature.
Non-metals are found on the right side of the periodic table, and they tend to be brittle and non-conductive. They can be solids, liquids, or gases at room temperature.
Metalloids are located along the zigzag line that separates the metals from the non-metals. They have properties of both metals and non-metals and can act as semiconductors.
The periodic table is organised in rows called periods and columns called groups. In general, metals are found in groups 1-12 and non-metals are found in groups 13-18. Metalloids can be found in groups 13-16. As you move from left to right across a period, the elements become less metallic and more non-metallic in their properties. As you move down a group, the reactivity of the elements tends to increase.
The periodic table organizes elements based on their properties, including metals, non-metals, and metalloids. Here is how they are organized:
1. Metals: Metals are found on the left side and in the middle of the periodic table. They generally have properties like luster (shininess), conductivity (ability to conduct heat and electricity), malleability (ability to be hammered into thin sheets), and ductility (ability to be drawn into wires).
2. Non-metals: Non-metals are found on the right side of the periodic table. They have properties that are typically opposite to those of metals. Non-metals are generally dull in appearance, poor conductors of heat and electricity, and brittle.
3. Metalloids: Metalloids are located along a diagonal line between metals and non-metals in the periodic table. They exhibit properties intermediate between metals and non-metals. Metalloids can have some metallic properties like conducting electricity but also show non-metallic properties like brittleness.
It's important to note that the properties of individual elements can vary, and some elements may exhibit properties of both metals and non-metals. The periodic table provides a comprehensive overview of how elements are categorized based on their properties.
