The electrostatic force exerted by a cation on an anion distorts its electron cloud, which has a tendency to move towards the cation. The degree of polarisation is directly proportional to the charge of the cation and indirectly proportional to its size.
Due to polarization, the ionic compound gains a certain degree of covalency.

∙ 15y agoPolarization has to do with how the electrons are being shared in a covalent bond. When two atoms with different electronegativities bond together, the valence electrons are unevenly shared between them. The more electronegative atom will pull the electrons of the bond closer to itslef because it has a strong "desire" for those electrons, thus making the bond polar.
Ex: HCF3 or trifluoromethane. The electrons between the carbon and fluorine reside closer to the fluorine because fluorine is more electronegative.

What elements are in ionic compounds?
Ionic compounds only occur between a nonmetal and metal, also Halogens and The Carbon Family do not form Ionic bonds.
Which compounds are ionic CO2 SrCl2 H2S or SO2?
Ionic compounds occur between atoms of a metal and a non-metal therefore: CO2 would not, SrCl2 would, H2S would not and SO2 would not. Only SrCl2 would be an ionic compound.
What are two physical properties that differ between covalent and ionic bonds?
There are more than two. In general: Covalent compounds have low melting and boiling points while ionic compounds have high melting and boiling points. Ionic compounds are good conductors of electricity when melted, while covalent compounds are not. Ionic compounds are soluble in water, while covalent compounds are soluble in non-polar liquids. These are the essentials, but other differences exist. All of these are generalizations, exceptions do occur.
Give the properties of ionic compounds?
There is one very important property of ionic compounds. Ionic compounds are compounds that will conduct electricity when dissolved in water.
Ionic compounds often have higher melting point than metals. Using at least 2 properties of ionic compounds explain why is cookware not made from ionic compounds?
1) Ionic compounds are not good heat conductors 2) Ionic compounds are not malleable

What are the types of polarization?
electronic polarization ionic or atomic polarization orientation or dipole polarization space charge polarization
What are atoms held together by a atratction between what?
The electrostaic attraction between atoms (a metal and a nonmetal) occur in ionic compounds.

What is the ionic charge of chlorine in its compounds?
In ionic chlorine compounds, the ionic charge of chlorine is -1.
What is the net ionic equation of lithium nitrate and sodium chloride?
Any reaction occur between these two compounds.
Common substances that form ionic compounds?
substances such as sodium and chlorine for ionic compounds basically it is neutral elements that form ionic compounds
How can molecular compounds be distinguished from ionic compounds?
Many ionic compounds exist as crystals but covalent compounds as molecules (there are exceptions as diamond though). Ionic compounds would be good electrical conductors unlike molecular compounds.
What do you call compounds that have been formed through ionic bonding?
Ionic compounds.
