Group-15 Elements

The strongest reducing agent amongst all the hydrides of Group 15 element is

Zeolites, 15th Group Elements, Hydrides OF 15th Group Elements Stablity, Oxides OF Nitrogen, Compounds OF Nitrogen

A hydride (X) of Group 15 element is distinctly basic and has unexpectably high boiling point. It reacts with NaOCl to give another hydride (Y), which is a strong reducing agent and is used in organic analysis. X and Y are

Give reasons for the following: (i) Oxygen is a gas but sulphur is a solid. (ii) O_(3) acts as a powerful oxidising agent. (iii) BiH_(3) is the strongest reducing agent amongst all the hydrides of Groups 15 elements.

Doping mens introduction of small amount of impurities like phosphorus , arsenic or boron into the pure crystal . In pure silicon , ther are four valenices used in bonding with other four adjacent silicon crystal is doped with a group -15 element ( with five valence electron ) such as P, As , or Bi , the structure of the crystal lattic remains unchanged . Out of the five valence electron of group -15 doped element four element are used in normal covalent bonding with silicon while fiffth electron is delcoasiled and thus conducts electricity Doping a silicon crystal with a group -13 element (with three valence electrons ) such as B, Al, Ga or In products a semiconductor with three electrons in in dopant . The place where fourth electron is missing is called an electron vacancy or hole . Such hole can move throught the crystal like a positive charge giving rise conduction of electricity. Silicon that has been dopend with group - 15 elements is called :
