Answer: Ionic compounds are "fixed" in their chemical composition as forces present between atoms of these compound are strong electrostatic forces of attraction due to which these compounds have fixed chemical composition.
Explanation:
Compounds formed by transfer of electrons from one atom to another are called ionic compounds.
For example, sodium atom on losing its one valence electron forms [tex]Na^{+}[/tex] ion and when a chlorine atom gains this electrons then it forms [tex]Cl^{-}[/tex] ion. These ions when come closer then an electrostatic force of attraction will pull them together forming NaCl compound.
Therefore, one atom of sodium is chemically combining to one atom of chlorine to form NaCl.
As the forces present between atoms of an ionic compound are strong electrostatic forces of attraction due to which these compounds have fixed chemical composition.
Thus, we can conclude that ionic compounds are "fixed" in their chemical composition as forces present between atoms of these compound are strong electrostatic forces of attraction due to which these compounds have fixed chemical composition.
Ionic compounds are formed when there is a donation of an electron from one element to another that receives the electron. This causes the donating atom to attain a positive charge and the receiving atom to attain a negative charge. The ions thus formed are held by strong electrostatic forces that hold them together.
- Ionic bonds are formed through the transfer of electrons from one element to another which receives the electron.
- Positive and negative ionic charges are thus acquired by the respective elements. Strong electrostatic forces that act in all directions hold the ions together.
- This also gives them the fixed state that makes it more difficult to break them up when compared to the covalent bonds.
- So, the strong electrostatic forces cause the fixed state of ionic compounds.
