Why AgBr shows both frenkel and schottky defect?
because the size of ions are enough to show both defects
Why does AgBr show both Frenkel and Schottky defects?
The radius ratio for AgBr is intermediate. Thus it shows both frenkel and schottky defects. The major defect in AgBr is the Frenkel defect. It has a rocksalt structure i.e. CCP lattice of of Br with atoms of Ag occupying all octahedral holes.Ag moves from octahedral to tetrahedral sites causing only cations to precipitate. Schottky defect arise due to missing of ions from their lacttice point and frenkel arise when the mmissing ions occupy interstitial sites. in AgBr, ag+ ion is small in size and when removed from lacttice point they can occupy interstitial site and therefore show both frenkel and schottky defect. SCHOTTKY Defect in AgBr is exhibited due to precipitation of both Cations and Anions.
Why AgBr shows both frenkel and schotky defect?
When the both the cations and anions are absent from the crystal lattice it is called Schottky defect. This defect is shown when the anions and cations have comparable size. The Frenkel defect is shown by ionic molecules when their is a large difference in the size of anions and cations. The smaller anions are very much mobile and they occupy interstitial site. AgBr has cations and anions with comparable size and hence it shows Schottky defect but the Ag+ ion is very much mobile and it easily occupies interstitial place getting dislocated from its original place, that's why the ionic crystal AgBr shows both Schottky and Frenkel defects.
What are the different types of congenital heart disease in adults?
The different types of congenital heart disease in adults are - Atrial septal defects, both secundum and primum, with closure often achieved with outpatient catheter-based techniques. - Ventricular septal defects. - Coarctation of the aorta. - Valvular defects. - Tetralogy of Fallot.
How does zim like dib?
He doesn't but if you are a ZADR supporter then I guess you could go with that they are both defects of their species and even defects need love.
Can you get an Army medical waiver if you have birth defects in both arms?
what are the birth defects? Can you still function normally? if so I'd say yes; if it is a handicap most likely no.
What is done during a cardiac catheterization to confirm septal defects?
To confirm septal defects, a catheterization measures oxygen content on both the left and right sides of the heart.
Are there any defects involved in cases where parents of a child are both o positive?
Not due to blood type.
Lipids and proteins are both types of?
They are both nutrients, or types of food
Are Microsoft Word and Microsoft Excel system softwares?
MS Word and MS Excel are examples of application software, because they allow the user to accomplish specific tasks. System software is software that runs in the background to make the system resources available to application software. An example of something system software does to assist applicatin software is allowing the computer to talk to the printer.
What birth defects are caused by genes and environmental factors?
A less understood cause of birth defects results from the interaction of genes from one or both parents plus environmental influences.Cleft lip and palate.Clubfoot.hydrocephalus.Diabetes mellitus.Heart defects.Some forms of cancer.
Choux and Phyllo are types of what?
