About Simulation

  • In this simulation, you will explore the physical properties of non-metals, such as non-lustrousness, softness, non-malleability, non-ductility, and poor electrical conductivity, within an interactive virtual environment.
  • You can explore and identify the non-lustrous nature of non-metals like graphite, sulphur, and iodine as part of the simulation.
  • You will measure and compare the softness levels of these non-metals using appropriate tools or qualitative assessments within the simulation.
  • Throughout the simulation, you can investigate and recognize the non-malleable and non-ductile characteristics exhibited by these non-metal elements.

Chemistry Practical Class

  • By participating in the simulation, you can conduct experiments to test and verify their poor conductivity of electricity compared to metals.

Description

Non-metal:
A non-metal in chemistry can be defined as a chemical element that generally, in a chemical reaction, gains electrons when it reacts with a metal. It tends to form an acid if combined with oxygen and hydrogen. The non-metals display more variety in colour and state in comparison to metals.

Properties of Non-metals
Examples of non-metals are chlorine, carbon, bromine, sulphur, phosphorus etc. They show the following properties :

Physical Properties of Non-metals:Some of the major physical properties of non-metals are given below.

  • Most of the non-metals are generally gaseous at room temperature.
  • Non-metals cannot be hammered into thin sheets. It means they don’t possess the property of malleability. Instead, they are brittle as they break down into pieces on hammering.
  • Non-metals are not ductile. They cannot be drawn into wires.
  • Non-metals are poor conductors of heat and electricity.
  • Non-metals are not lustrous, which means they are not shiny instead of dull in appearance.
  • Non-metals have low tensile strength. It means they cannot hold heavyweights.
  • Non-metals are not sonorous. It means when we strike them, they do not make any sound.
  • Non-metals are soft. It means they can be cut by knife easily.
