What is the difference between pentavalent and trivalent atom?
Pentavalent atoms are the one containing 5 electrons in their valence shell while trivalent atoms containg 3 electrons in their valence shell e.g of penta. phosphorus,arsenic e.g of tri. boron, indium.
Why pentavalent bismuth is a strong reducing agent?
Well, it is NOT! It is an oxidizing agent because it is itself easily reduced to trivalent bismuth.
What happens when divalent impurity is doped with trivalent element?
will there be any structural changes when divalent is doped with trivalent
What are trivalent atoms often reffered to as?
elements having 3 electrons in its outermost orbit is known as trivalent atom
How many valance electrons are in trivalent atoms?
14
When a diode is doped with either a pentavalent or a trivalent impurity its resistance will be?
it will increase
How n type and p type material made?
pentavalent and trivalent atoms
Is NF4 a possible compound of nitrogen and fluorine?
No. Nitrogen is trivalent as this achieves the octet. heavier members of group 15 are trivalent and pentavalent.
Why pentavalent or trivalent impurities are used in p-n junction?
To increase the conductivity of diode
What elements are trivalent?
A trivalent element is one that can form up to three bonds to other elements. Nitrogen is the most common trivalent non-metal and aluminum is the most common trivalent metal.

What are trivalent and pentavalent impurities?
Doping is the process of adding impurity atoms to intrinsic silicon or germanium to improve the conductivity of the semiconductor. The term impurity is used to describe the doping elements. Two element types are used for doping: trivalent and pentavalent. A trivalent element is one that has three valence electrons A pentavalent element is one that has five valence electrons. When trivalent atoms are added to intrinsic semiconductors, the resulting material is called a p-type material. When pentavalent impurity atoms are used, the resulting material is called an n-type material. The most commonly used doping elements are listed below. Commonly Used Doping Elements Trivalent Impurities To make p-type Aluminum (Al) Gallium (Ga) Boron (B) Indium (In) Pentavalent Impurities To make n-type Phosphorus (P) Arsenic (As) Antimony (Sb) Bismuth (Bi)
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.
What are p type semiconductors?
P type semiconductors have been doped with trivalent elements, causing them to conduct via "hole" flow. N type semiconductors have been doped with pentavalent elements, causing them to conduct via electron flow.
Which is the pentavalent impurity is boron or germanium or indium or antimony?
Which is the pentavalent impurity is boron or germanium or indium or antimony
What is trivalent?
those atoms have 3 valency is called trivalent.
