​Concept:

Ionic bond, also called the electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.

  • Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
  • The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion).
  • Example of NaCl

F1 Aman Madhu 23.10.20 D3

Explanation:

  • Ionic bond is formed by the complete transfer of one or more electrons from one atom to another.
  • Ionic bond is a chemical bond formed by the electrostatic attraction between oppositely charged ions.

NaCl has an ionic bond:

Na, atomic number 11, has electronic configuration- 2, 8, 1, that is, it has one electron more than the nearest noble gas configuration, Neon (Atomic number- 10).

Cl (atomic number) 17, has electronic configuration- 2, 8, 7, that is, it is one electron short of the nearest noble gas configuration, Argon (Atomic number- 18).

Therefore, Sodium readily loses the one electron which is gained by chlorine, thus, completing their octets and forming an ionic bond.
