None - unless they're in the oxide form.
Conductive materials: they are good conductors of heat or electricity. Nonconductive materials: they are not good conductors of heat or electricity.
The three main metals in a periodic table are transition metals, alkali metals, and alakaline earth metals.
They are Metals
all are non metals
non-metals .... alkali metals....transition metals....alkali earth metals....rare earth metals....other metals....halogens....inert elements
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.
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.
Conductive materials: they are good conductors of heat or electricity. Nonconductive materials: they are not good conductors of heat or electricity.
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.
If you mean "dis"allow the flow, it's because electrons cannot travel easily between the atoms of the material.

what are the characteristics of metals? metals? non-metals?
metals
Metals, non metals and metaloids (which have some of the properties of both metals and non metals).
They are in between the metals and non metals
