no..silican cannot produce electricity in large quantity's because of the material its made up off
Atoms can be broken down, so it is a quark or a lepton.
Glass is an electrical insulator. It does not conduct electricity. Many insulators made for power transmission lines or in the older days telephone or telegraph insulators, are made out of glass due to their superior insulating qualities.
For a material to conduct electricity it needs to have free charge carriers. I.e. particles with charge that can move around the material. Distilled water, or pure water only contains H2O molecules, which are neutral. Rainwater on the other hand also contains other materials such as salt, which in water falls apart into positive and negative ions. These are serviceable charge carriers, and therefore rainwater can conduct electricity.
Insulator.
Gold is the material that conducts electricity but cannot be pulled into wires. This is unlike the other materials like aluminum, copper and steel.
You cannot get electricity from coal. Electricity and coal are two very different types of material.
insulator; I think porcelain.hopefully.

If you mean "dis"allow the flow, it's because electrons cannot travel easily between the atoms of the material.
Dissolved and liquid salts are electrolytes and do conduct electricity. All natural waters have salts in them. Water only conducts electricity, when salts have dissolved in the water. Distilled water aka water without any salts is a nonelectrolyte and does not, as any other oxide, conduct electricity.
Who? Semiconductors were first discovered in 1833 by Michael Faraday while working at the Royal Institute in London. The first material which he realised had the properties of semi-conductance was silver sulphide, the black tarnish that appears on Silver if you don't polish it for a while. Why are they useful? Normally they do not conduct electricity, but when a voltage is applied to them, they change so they do conduct electricity. A practical example is a transistor, which is like a switch with no moving parts. When no voltage is applied to the semiconductor, the switch is effectively open (the electricity cannot flow). When a voltage is applied, the switch is effectively closed (the semiconductor conducts, so the electricity can flow through it).
The transistor. It has 3 connections on it, an in, an out, and a gate. If no electrical charge is present at the gate, it conducts electricity from the in to the out. It a charge is applied to the gate, electricity cannot flow. Single transistors are extremely small, made of 3 layers of silicon. Most are nearly, if not completely, microscopic.
If it were a cream for example water-in-oil * warmer to the skin * does not conduct electricity *Can be dyed with Sudan III *Cannot be with Food colouring oil-in-water *cooler to the touch *conducts electricity *not dyed by Sudan III *can be dyed with food colouring
