Why is it essential to earth electrical appliances having metallic body?
Nitin1996
if the appliance shorts out (if one or more of the wires inside it come into contact with the outer casing) the electricity will take the shortest route to be neutralised. If there is no earth wire and you touch the shorted out appliance then the shortest route to neutralise the electric charge is through you, and you will be electrocuted. If an earth wire is present then the shortest route to neutralise the current will be through this wire, so you would not be electrocuted if you touched the shorted out appliance.

If a mineral has no streak is it metallic?
When identifying minerals, having no streak is a property of hardness. A streak plate has a hardness of ~7(Moh's Scale). Thus any mineral having a hardness greater than 7 will have no streak.Metallic is the description of luster. Or the general appearance of a mineral surface in reflected light.If you were refering to the mineral having metal elements in it, streak is actually very useful for identifying them. Many minerals that are composed of non-metals have a white streak which can appear to be no streak, however there are also many minerals with no streak which are composed of non-metallic minerals (Diamond).

The first 20 elements that are cations?
Elements by definition are electrical neutral and therefore are not cations, which have a positive electrical charge. The first (i.e., those having the lowest atomic numbers) 20 elements that commonly form cations during chemical reaction are hydrogen, lithium, beryllium, sodium, magnesium, aluminum, potassium, calcium, scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, gallium, and arsenic.

Why is an electrical appliance safe to use?
All appliances have to pass an inspection to insure the safety of that device. These inspection rules are generated by an independent safety authority. In Canada it is CSA, Canadian Standards Association and in the US it is UL, Underwriters Laboratories.Electricians working under the electrical code can not connect any piece of equipment to the utility's electrical supply without the device having a CSA or UL label on it.This is becoming a problem with China exporting equipment to North America. Many electrical appliances from China would not pass inspection of the CSA or UL requirements. As of late the CSA and UL labels are being forged and are applied to the exported appliances from China.So the old adage of "buyer be aware" comes into full effect. Before buying appliances do your research and find out from which country the equipment comes from.
