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.

A pentavalent atom has 5 valence electrons, meaning it can form up to 5 chemical bonds, while a trivalent atom has 3 valence electrons and can form up to 3 chemical bonds. The valency of an atom determines how it can bond with other atoms to form molecules.

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

What are trivalent atoms often reffered to as?
Trivalent atoms are often referred to as having a valency of 3. This means they can form three chemical bonds with other atoms. Examples of trivalent atoms include boron, aluminum, and nitrogen.
What is the difference between carbon atom and nitrogen atom?
they like have bigger particles nd stuff
Is the difference between helium in a jar in helium?
helium in a jar diff from helium atom
What is the energy difference between the 1st and 3rd energy levels in the hydrogen atom?
The energy difference between the 1st and 3rd energy levels in a hydrogen atom is greater than the energy difference between adjacent levels. This energy difference can be calculated using the Rydberg formula or the Bohr model equation for energy levels in hydrogen.
When metal atom loses electron energy is?
When a metal atom loses an electron, it loses energy. This energy corresponds to the difference in energy levels between the electron's initial position and its final position outside the atom.
What is the difference between trivalent and ternary?
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.
What elements are used as impurities for doping germanium and silicon?
For doping germanium and silicon, commonly used elements are phosphorus, arsenic, and antimony as donor impurities to create n-type semiconductors, and boron, gallium, and indium as acceptor impurities to create p-type semiconductors.
Which is the pentavalent impurity is boron or germanium or indium or antimony?
The pentavalent impurity among the options provided is antimony. Antimony has a valence of +5, meaning it can substitute for a pentavalent atom in a crystal lattice.
How are P and N type semiconductors formed?
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.
An atom with 5 free electrons is said to be?
An atom with 5 free electrons is said to be pentavalent.
What is the nature of bonds in N type and P type semi conductors?
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.

What is a pantavelant atom?
There is no scientific reference to a "pantavelant atom." It appears to be a term that does not have a recognized meaning in the field of chemistry or physics.
