Question

the usage of metals and non-metals

Answer 1

The usage of metals:
1. strong
2. malleable and ductile
3. react with oxygen to basic oxides
4. sonorous
5. high melting and boling point
6. good conductor of electricity
7. good conductor of heat
8. mainly solids at room temperature exception mercury liquid at room temperature
9. shiny when polished
10. when they from ions, the ions are positive
11. high density

The usage of non metals:
1. brittle
2. brittle
3. react with oxygen to from acidic oxides
4. dull sound when hit with hammer
5. low melting and boling point
6. poor conductor of electricity
7. bad conductor of heat
8. solids, liquids and gases at room temperature.
9. dull looking
10. when they forms ions, the ion are negative except hydrogen that forms a positive ion, H+
11. low density
