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.
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.
Both.
Both are alkali metals. Both are minerals. Both are never found in nature. Have an inverse relationship in the body - as one increases, the other decreases
Both. An acid and base can both be corrosive to the skin and other materials.
Both are glassy and both are black
because the size of ions are enough to show both defects

Both Frenkel and Schotty defects improve the electrical conductivity of an ionic crystal.
1).schottky defect arises due to departue of ions (both cation and anion in equal ratio) from crystal lattice leaving holes that favour conductivity. The equal no of ions depart because to maintain the electrical neutrality of crystal. It was discovered by walter.H schottky in 1930. But in frenkel defect ions(cations) are missing from there normal lattice site and occupying an interstitial site between the lattice points. They dont depart from crystal lattice. Because no departure occure so crystal remain electrically neutral. It was discovered by Yakov frenkel in 1926. 2) schottky defect is only vacancy defect but frenkel defect is vacancy as well as interstitial defect. 3). Schottky defect decreases density and strength of the crystal. But frenkel defect doesnt affect density. 4).schottky defect is shown by the ionic solids having high coordination no and approx. same size of cation and anion(i.e r+ve/r-ve approaches to 1) While frenkel defect is shown by the compound having low coordination no and size of anion larger than cation(i.e r+ve/r-ve approches the minimum value).

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.
what are the birth defects? Can you still function normally? if so I'd say yes; if it is a handicap most likely no.
To confirm septal defects, a catheterization measures oxygen content on both the left and right sides of the heart.
Not due to blood type.
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.
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.
Smoking and drinking are both harmful while you are pregnant. These activities can compromise your baby's development and may lead to defects.
