carbon and sulphur
Non-metals generally do not conduct electricity as well as metals due to their atomic structure. Metals have free electrons that allow for the easy flow of electric current, whereas non-metals typically lack these free electrons, resulting in poor conductivity. Additionally, non-metals often have higher ionization energies and electronegativities, which further inhibit their ability to conduct electricity. As a result, non-metals are often considered insulators.
No, the most naturally occurring elements are not all metals. The majority of elements on the periodic table are metals, but non-metal elements also occur naturally. Examples of non-metals include oxygen, nitrogen, and carbon.
all are non metals
Most non-metals do not have shiny appearances. They often have dull or non-reflective surfaces due to their lack of free electrons that can move around and reflect light. Some non-metals like iodine or graphite can appear shiny under certain conditions, but this is not common.
Selenium is a non metal, and non metals are poor conductors due to the lack of free electrons or ions.
Non metals do not conduct heat. They have high resistance.They are insulators.Non metals do not have a pool of 'free electrons' (as metals do with metallic bonds). Hence they generally are poor conductors of heat. Nonmetals such as Styrofoam are widely used as insulators. Graphite is an exception as it is a good conductor of heat with its free electrons.Most of the non metals does not conductors because the do not have free electrons. But graphite is a good conductor. Most of the non metals are insulators.
Mostly gases
Non-metals are any of the non-metallic elements found in Groups 14, 15 and 16 of the periodic table. At room temperature, most non-metals exist as either gases or solids.
Metals can conduct electricity because they have free electrons that can move easily between atoms, allowing electricity to flow. Non-metals, on the other hand, generally do not conduct electricity well because they do not have free electrons available for conduction.
The only non-metal that occurs in a liquid state at room temperatures is bromine (Br).
No, the most naturally occurring elements are not all metals. The majority of elements on the periodic table are metals, but non-metal elements also occur naturally. Examples of non-metals include oxygen, nitrogen, and carbon.

No reaction happens. Only way to get a reaction going is if you have two molecules with different Metals and Non-metals. Metals in this one are different but non-metals are not so no reaction.
Non-metals like graphite and doped silicon can conduct electricity due to the presence of free electrons that allow for electron movement. However, most non-metals are poor conductors of electricity as they lack the free electrons needed for conduction.
Non-metals do not show displacement reactions because they are less reactive than metals. Displacement reactions occur when a more reactive element displaces a less reactive element from its compound. Since non-metals are not as reactive as metals, they are not typically displaced in reactions.
Metals have large number of free electrons, which are responsible for conduction of heat, electric current, etc. Hence metals are good conductors. Non-metal don't have such free electrons in them. Hence they are bad conductors. There are many such properties which differentiate metals from non-metals. for example, metals have a typical metallic luster ( except few), etc.
