None - unless they're in the oxide form.
all are non metals
non-metals .... alkali metals....transition metals....alkali earth metals....rare earth metals....other metals....halogens....inert elements
Metals are located to the left of the stair-step line on the periodic table.
metals on left, non-metals on right, some others in middle.
No, it is not true. When metals loose electrons they become cations.
Yes. Rubber is electrically nonconductive.
any material that will not allow electricity to pass through it. rubber, plastic, some electrically conductive materials are metals, esp. gold, water, neon gases insulators, glass, paper :)
gold silver and copper can not be conducted.
Conductive substances allow the flow of electricity due to their ability to carry an electric current, whereas nonconductive substances do not allow the flow of electricity. Conductive substances typically have free-moving electrons, while nonconductive substances have tightly bound electrons that do not facilitate the movement of electric charges.
Pollution Degree 1: No pollution or only dry, nonconductive pollution occurs. The pollution has no effect. Pollution Degree 2: Normally only nonconductive pollution occurs. Temporary conductivity caused by condensation is to be expected. Pollution Degree 3: Conductive pollution or dry nonconductive pollution that becomes conductive due to condensation occurs. To be found in industrial environment or construction sites (harsh environments). Pollution Degree 4: The pollution generates persistent conductivity caused by conductive dust, rain, or snow.

If you mean "dis"allow the flow, it's because electrons cannot travel easily between the atoms of the material.
Flux is used to keep metals from oxidizing. Solder will not bond well with copper-oxides which are formed when copper is exposed to high temperatures (ie a soldering iron) the flux prevents the oxidation. If you were to solder without flux the solder joint would be weak and possibly completely nonconductive.
Silicon tetrachloride is a nonconductive compound in its pure form. It does not conduct electricity because it does not contain free-moving electrons that are necessary for conducting electricity.
what are the characteristics of metals? metals? non-metals?
metals
They are metals.
