This is because the outermost or valence electrons experience very less attraction from the nucleus. Thus those electrons are easily attracted and hence making the ion polarised.

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.
Why aluminum Fluoride is more ionic than aluminum Chloride?
Cl has large anion size its polarizibility is higher than fsa it forms covalent compds
How is an ionic bond held together?
It is held together by electrostatic attraction between the ions in the compound. In the bond, there is a complete transfer of electrons between the atoms, so this makes the cation lose electrons and the anion gain electrons. The cation becomes positive and the anion becomes negative, and therefore there is a large attraction between the atoms.
What is Fajan's rule?
Fajans' Rules, formulated by Kazimierz Fajans in 1923, are used to predict whether a chemical bond will be covalentor ionic, and depend on the charge on the cation and the relative sizes of the cation and anion.IonicCovalentLow positive chargeHigh positive chargeLarge cationSmall cationSmall anionLarge anionThus sodium chloride (with a low positive charge (+1), a fairly large cation (~1 Å) and relatively small anion (2Å) is ionic; but aluminum iodide (AlI3) (with a high positive charge (+3) and a large anion) is covalent.
Is anion an example of anabolism?
In a dehydration, which is also called a condensation reaction, water molecules are being removed and new bonds are forming(peptide linkages, glycosydic linkages and ester linkages), therefore it is an anabolic reaction.
Why are large cations precipitated by large anions from aqueous solutions?
because of lattice energy
What would happen to a resting membrane potential if the concentration of a large intracellular anions that are unable to cross the membrane experimentally is increased?
If the concentration of large intracellular anions..i.e. proteins, which are unable to cross the membrane due to their large size.. were to increase, the resting potential would reach a more negative state, a deviation from -70mV to a more negative value do to these anions.

Why does lithium form stable complex compound than other alkali metals?
As complex comopunds or salts are those which can dissociate to give complex anion and simple cation and vice versa. As Li is small in size and if Li combine with comples anion then it will form a complex compounds.While the other alkali metals are large in size. So if these metals combine with large anion or complex anion then they does not form a complex compounds. It is the reason that Cation which is in the form of alkali is large or complex and anion also comple. So, in this case both ions that produced are large.That's why other then Li, alkali metals not form comples compounds. One of the best example of Li complex compound is " Lithium tetra-amine " Li(NH3)4
What is the element group called carbonate?
"Carbonate" is not an element or an element group; instead, it is a polyatomic anion and is one of a large group of oxyanions.
Why aluminum Fluoride is more ionic than aluminum Chloride?
Cl has large anion size its polarizibility is higher than fsa it forms covalent compds
Why polar bears are dangerous?
Because they are large, powerful predators, and are very capable of killing a human easily.
What are the advantages to pie charts?
summarize large amount of data in visual formis easily understoodData can be easily compared
Are large grains easily seen as fine grained?
Large grains are easier to see than fine grains.
