metals are hard,lustrous, malleable, ductile, sonorousand good conductors of heat and electricity.The materials which have this properties are called metals. Non metals are soft and dull when we take it into hand press hard they convert into powder.They are poor conductors of heat and electricity.
Metals:
1. Solid at room temperature (except Mercury)
2. Shiny/lustrous; mostly silvery white in color (except copper and gold)
3. high melting and boiling point (except the alkali metals)
4. hard and strong
5. malleable and ductile
6. high density
7. good conductors of heat and electricity
8. sonorous
Non-Metals:
1. Gases, volatile liquids or solids
2. dull if solid/non-lustrous, various in colors
3. low melting and boiling point (except carbon and silicon)
4. not uniform in hardness and strength
5. brittle if solid, not malleable, not ductile
6. low density
7. poor conductors of heat (except carbon (diamond and graphite)), non conductors of electricity (except carbon (graphite))
metals electropositive, basicity, hard, ductile, malleable, sonorous
nonmetals electronegative, acidic, brittle, and not all the other three properties.
chemical propertiy of non metal is it react with acids
Sodium chloride is a compound, not a chemical element.
Germanium has properties of both metal and non-metal. Hence it is considered to be metalloid.
The properties of a metal are of follows, a pure chemical composition, a pure chemical composition is a element, or a compound in pure form. As well as a metallic luster (when it is shiny and if melted or filed flat it looks like a mirror. Now pure chemical composition is hard to test with solid metal, but a metallic luster should do the trick usually, and if it is being melted, than you should see that is is a pure chemical composition by looking if parts of it have different melting speeds.
the product's properties usually and may differ from the properties of the reactants. Example-salt-sodium, a soft explosive metal and chlorine, a toxic gas. make salt.
chemical propertiy of non metal is it react with acids
Physical: malleability of the wire Density of the brackets Chemical: they are non toxic
The differences between metal and non-metals are their chemical properties. Metals usually have 1-3 electrons on their outer shells, and non metals have 4-8 electrons in their outer shells.
Non-metal
Magnesium chloride is a chemical compound and is therefore not a metal. It is ionic and is not metallic in its properties. Non-metal usually refers to elements.
It's a non metal, it's atomic number is 1, and it's atomic mass is about 1.
a gas
Non-metal
metal- shiny non-metal- dull
It has all the properties of a metal and not a non-metal
Because it doesn't have the properties of a metal.
Some chemical properties of metals are that they have good electrical and thermal conductivity. Metal also form positive ions or cations and ionic bonds. When exposed to air and moisture, many metals tend to corrode.
