1) distinguish between metals and non metals
Answers
Answer:
Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).
In the elemental form, non-metals can be gas, liquid or solid. They aren't shiny (lustrous) and they don't conduct heat or electricity well. Usually their melting points are lower than for metals, although there are exceptions. The solids usually break easily, and can't bend like metals

Answer:
Distinguish between Metals and Non - metals:-
Metals:-
1. These are solids at room temperature except mercury.
2. These are very hard except sodium.
3. These are malleable and ductile.
4. These are shiny.
5. They have high densities.
Non-Metals:-
1. These exist in all three states.
2. These are soft except diamond.
3. These are brittle and can break down into pieces.
4. These are non-lustrous except iodine.
5. They have low densities.
