Though germanium diodes were the first ones fabricated, several factors make silicon the choice vs. germanium diodes. Silicon diodes have a greater ease of processing, lower cost, greater power handling, less leakage and more stable temperature characteristics than germanium diodes. Germanium diodes' lower forward drop (.2V to .3V versus .7V to 1.0V) make them better at small signal detection and rectification.

Can non metals conduct electricity?
Generally non metals are poor conductors of electricity as they do not have free electrons. One notable exception is graphite where there is delocalisation of electrons which gives rise to conductivity. The metalloids such a s silicon are semiconductors, in their case exciting electrons into what chemists would call "antibonding" orbitals but physicists call conductance bands allows limited conductivity.
What is the term for a type of cell that converts the Suns energy into electrical energy by releasing from silicon?
This would be called a photocell.

Why is silicon called a semiconductor?
silics meaning what were more generally termed "the flints" or "Hard Rocks" during the Early Modern era where nowadays as we would say "silica" or "silicates"), and was later mistaken by Humphry Davy in 1800 for a compound. In 1811 Gay-Lussac and Thénard probably prepared impure amorphous silicon through the heating of potassium with silicon tetrafluoride. It was first discovered as an element by Berzelius in 1823. In 1824, Berzelius prepared amorphous silicon using approximately the same method as Lussac. Berzelius also purified the product by repeatedly washing it. Because silicon is an important element in semiconductors and high-tech devices, the high-tech region of Silicon Valley, California is named after this element. silicon is so named because they are the compositions including silica content
What element is not a good conductor or a good insulator?
I'm assuming electrical conductor - Several spring to mind. Carbon is pretty bad at conducting electricity but it will do it, which is why electrical resistors are made of them. Semiconductors such as Silicon and Germanium can be coerced into conducting electricity when atomically altered by a doping process. These last two are what make this website (and every single website on the planet) possible. These two elements are used to make the single most important thing in the computing world - No not Microsoft or Apple - They make the transistor, invented over 50 years ago but without which modern computers would not exist.
What is another element that is similar to silicon that is not germanium?
Carbon in the form of diamond or nanotubes. Tin and Lead would be, but they are metals instead.
Would it be true to say that silicon and germanium are used as alloys?
yes we silicon is a alloy.
Which element would you expect to have the most similar chemical behavior to Silicon?
Germanium
Which metalloids both are in group 14 and are used to make computer chips?
The metalloids silicon and germanium, also in Group 14,are used to make computer chips.
Which elements would you use to predict properties of ekasilicon?
Ekasilicon was the name appointed by Mendeleev to the undiscovered germanium; germanium has similar chemical properties to silicon and tin.
I am researching germanium and i would like to know what can you find it in?
You can find Germanium inside transistors. Note. Most transistors today are made from Silicon. In order to find a Germanium transistor you can read the type no. off the device, then look in a data book. Alternatively, if you have the equipment, measure Vcesat for the device. Silicon devices show about 1.2 V. When you find one at about 0.6 V you've got your Germanium.
What will be the result if silicon diode is replaced by the germinium diode?
The built is voltage would be lower than silicon diode,more leakage or reverse saturation current,poor thermal stability,high noise and greater conduction in comparison to silicon diodes.
Which element would you expect to behave the most like carbon (C)?
Silicon (Si) behaves most like Carbon (C).
This atom in its unbound state has four valence electrons?
That would be carbon (C), silicon (Si), germanium (Ge), Tin (Sn), etc.
What elements are used as impurities for doping germanium and silicon?
Any Pentavalent or Trivalent atom can be added to Silicon to create an "N" type or "P" type Material respectively. Which is used to create a PN Junction. Examples of Pentavalent atoms would be arsenic, antimony, and phosphorus, these Pentavalent atoms would be used to create an "N" Type material. Examples of Trivalent atoms are aluminum, boron, and gallium. Trivalent atom would be used to create "P" type material. I don't know why you would dope germanium, unless your talking about very old technology. Germanium use has slowed to a crawl since the discovery of intrinsic (pure) silicon.
How was germanium discovered?
In 1886 a German chemist named, Clemens A. Winkler discovered germanium. He discovered the first trace of germanium in the mineral argyrodite, while isolating it. (But germanium rarely makes distinct minerals.) He purified it to find the new element. Before this in 1871 a chemist named, Mendeleev predicted there would be a new element, that would have properties similar to the ones in silicon. His predictions were proved to be true.
