what is ionic bond?
Answers
Answer:
Ionic bonds are the bonds which are formed by transfer of electrons..
An ionic bond is the bond formed between a cation and and an anion.
• An ionic bond is formed by the transfer of valence electrons from the atom of an electropositive element to the atom of an electronegative element.
• Therefore, an ionic bond is also called an electrovalent bond.
• Ionic bonds are held together by strong electrostatic force of attraction acting between the cation and the anion.
• For example - NaCl is an ionic bond.
Na (2, 8, 1) has 1 valence electron, and Cl (2, 8, 7) has 7 valence electrons.
Now, Na has one electron excess of octet and Cl has one electron deficient of octet.
• Therefore, Na donates or transfers its single extra electron to Cl forming an ionic bond of Na⁺Cl⁻.
