Hey there!:
* S,and Ne are non-metals.
* Si is a metalloid.Generally metalloids acts as semiconductor.
* Ag and Hg are metals because metals exhibits lustre property, melleable and ductility properties.
Hope this helps!
Explanation:
Metals are the substances which lose electrons to attain stability and hence they form cations.
Metals are good conductors of heat and electricity and generally they are solid at room temperature. Metals have a shiny surface and they are also malleable and ductile.
For example, Ag: Silver Shiny solid at room temperature that is also a good conductor of heat and electricity. Hence, silver is a metal.
Non-metals are the substances which gain electrons to gain stability and hence they form anions.
Non-metals are bad conductors of heat and electricity. They are brittle and non-shiny in nature.
For example, S: Sulfur Powdery yellow solid is a non-metal.
Metalloids are the substances which show properties of both metals and non-metals.
Metalloids are moderately able to conduct heat and electricity. Generally metalloids are solid at room temperature. They are also able to react with other molecules.
For example, Si: Silicon Semiconductor is a metalloid.
Hence, the given substances are classified as follows.
