What is metal and non metal?

Question

Answer

Answer

¶¶ Metals are materials holding or possessing the characteristics of being shiny, hard, fusible, malleable, ductile, etc. Few examples of metals (materials) are – Gold, Silver.

¶¶ Non-metals are the elements that do not conduct heat and electricity and are neither malleable nor ductile. Example: Carbon, sulphur, phosphorus, silicon and oxygen.

Answer

Metal is a material which have a lustrous appearance , they can conduct electricity and heat and are ductile and malleable.

Non metals have the properties opposite of the metals . they can't conduct electricity or heat , r not lustrous and aren't ductile or malleable.

Answer

Metal and Non-metal

Metal and non-metal are two categories of elements based on their physical and chemical properties. Metals are generally hard, shiny, ductile, malleable, and good conductors of heat and electricity. They tend to lose electrons and form positive ions in chemical reactions. Non-metals, on the other hand, are generally dull, brittle, non-ductile, non-malleable, and poor conductors of heat and electricity. They tend to gain electrons and form negative ions in chemical reactions.

Physical Properties of Metals

Metals have the following physical properties:

- Hardness: Metals are generally hard and strong.
- Malleability: Metals can be pounded into thin sheets without breaking.
- Ductility: Metals can be drawn into thin wires.
- Shiny Appearance: Most metals have a shiny appearance when they are freshly polished.
- High Melting Points: Metals have high melting points.
- Good Conductors: Metals are good conductors of electricity and heat.
- Density: Metals are generally dense.

Chemical Properties of Metals

Metals have the following chemical properties:

- Reactivity: Metals are generally reactive and tend to lose electrons to form positive ions.
- Corrosion: Metals tend to corrode when exposed to air, moisture, or acids.
- Oxidation: Metals tend to oxidize when exposed to air, forming a layer of oxide on the surface.
- Electropositivity: Metals have a tendency to give away electrons, creating positively charged ions.

Physical Properties of Non-metals

Non-metals have the following physical properties:

- Lack of Luster: Non-metals are generally dull in appearance.
- Brittle: Non-metals are generally brittle and easily break.
- Non-malleable: Non-metals cannot be pounded into thin sheets.
- Non-ductile: Non-metals cannot be drawn into thin wires.
- Low Melting Points: Non-metals have low melting points.
- Poor Conductors: Non-metals are poor conductors of electricity and heat.
- Low Density: Non-metals are generally less dense than metals.

Chemical Properties of Non-metals

Non-metals have the following chemical properties:

- Reactivity: Non-metals are generally less reactive than metals.
- Tendency to Gain Electrons: Non-metals tend to gain electrons to form negative ions.
- Non-Corrosive: Non-metals are generally non-corrosive and do not rust or tarnish easily.
- Non-Oxidizing: Non-metals do not oxidize easily and do not form oxides.

Conclusion

Metal and non-metal are two different categories of elements based on their physical and chemical properties. Metals are generally hard, shiny, ductile, malleable, and good conductors of heat and electricity, while non-metals are generally dull, brittle, non-ductile, non-malleable, and poor conductors of heat and electricity. Metals tend to lose electrons and form positive ions in chemical reactions, while non-metals tend to gain electrons and form negative ions.
