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.
pentavalent- impurtity atoms containing 5 electrons. when pentavalent impurities are doped with intrinsic n type semiconductors are formed.
eg--> arsenic,antimony
trivalent- impurtity atoms containing 3 electrons. when trivalen impurities are doped with intrinsic p type semiconductors are formed.
eg-->indium
elements have a property of trivalent valence as Al+3
It has five (penta means five) electrons in its outer most (valence) shell. These are the only electrons that interact with other atoms.
Acceptor atoms
elements having 3 electrons in its outermost orbit is known as trivalent atom
they like have bigger particles nd stuff
No. Ferrous and ferric cations are divalent and trivalent respectively, but both are only single atom ions.
The number of electrons.

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.
Ternary means "composed of three items", while trivalent specifically refers to the ability of an atom or group of atoms to bind 3 monovalent atoms in a compound.
Valence state is sometimes used inseaf of the term oxidation state. Sometimes it just means yhe "valency" exhibited by an atom in a molecule. Valency is an old term that describes the number of bonds that an atom has formed in a molecule, for in /HNO3 nitrogen is 5 valent (pentavalent) in ammonia it is 3 valent, trivalent.

FORMATION OF P-TYPE SEMI CONDUCTOR A P - type semiconductor is formed when a small amount of trivalent impurity is added to pure Germenium or silicon atom crystal. The addition of trivalent impurity produces a large no. of holes to the host crystals. To explain the formation of P - type semiconductor, let usintroduce a trivalent impurity into the lattice of a pure silicon crystal. The trivalent atom has 3 valanceelectrons and form covalent bonds with neighbouring atoms. The 4th bond is incomplete . the trivalent atom then attracts an electron from an adjacent atom there bycompleting the 4th bond and forming a hole in the adjacent atom. Since a trivalent impurity atom provides 1 hole, an enormous increase occurs in the number of holes. The impure crystals so obtained is called P - type semiconductor where P represents the positive charge on hole. Thus the majority carrier in a P - type semiconductor are holes. Freeelectrons are also present in the P - type semiconductor. These are thermally generated and since they relatively few, they are called minority carriers. The trivalent impurity atoms are called acceptors because each accepts an electron when the atom is introduced into the host crystal.FORMATION OF N TYPE SEMI CONDUCTORAn N - type semiconductor is formed when a small amount of pentavalent impurity is added to a pure Germenium or Silicon crystal. The addition of pentavalent impurity produces a large no. of free electrons in the host crystal.To explain the formation of N - type semiconductor, let us introduce a pentavalent impurity atom into the lattice of pure silicon crystal. The pentavalent atom has 5 valance electrons, but only 4 form covalent bonds with the neighbouring atoms. The 5th electron finds no place in the covalent bonding so becomes free. Since an impurity atom provides one free electron, an enormous increase occurs in the no. of free electrons. The impure semiconductor so obtained is then called as N - type semiconductor where N represents negative charge on an electron. Thus the majority carrier in N - type semiconductor are free electrons. Holes are also present in the N - type semiconductor. These are thermally generated and since they are relatively few, they are called minority carrier.The pentavalent impurity atom are called donour because each donate a free electron to the host crystal.
A pentavalent atom is one that can form 5 chemical bonds, for example nitrogen in HNO3, phosphorus in PCl5.

The bonds in a N type or a P type semiconductor depends upon the impurity added into it. For example a trivalent impurity is added then three bonds will be formed by each atom and it becomes a P-type semiconductor whereas if a pentavalent impurity is added then five bonds will be formed by each and every atom and it becomes a N-type semiconductor.
The difference between a hydrogen atom and atomic hydrogen is that the "hydrogen atom" represents one atom of the chemical element hydrogen. Atomic hydrogen are isolated hydrogen atoms.
