Physical Properties of Metals & Non Metals | Class 9 & 10 Chemistry | NTSE | CBSE Board | Poonam mam
The Truth Show・2 minutes read
The lecture covers the physical properties of metals and non-metals, focusing on their existence in different states, conductivity, melting points, and other characteristics that differentiate the two groups. Various properties discussed include malleability, ductility, conductivity, density, luster, sonority, hardness, and exceptions within each category.
Insights
- Metals generally have high melting points and are solid at room temperature, with exceptions like Gallium and Francium existing in liquid form. Non-metals, on the other hand, are mostly solid or gaseous, with bromine being the sole liquid non-metal, showcasing the diverse physical states of these elements.
- The distinction between metals and non-metals extends to various properties like malleability, ductility, thermal and electrical conductivity, density, and sonority, highlighting the contrasting characteristics of these two groups. While metals excel in conducting heat and electricity, being lustrous, and having high densities, non-metals exhibit lower densities, poor conductivity, and lack luster, emphasizing the fundamental differences between these elemental categories.
