Who invented ionic bond
Electrovalency: The number of valence electrons either lost or gained by an atom during the ionic bond formation is called electrovalency. Note: The electronegativity difference between Li 1. Hence they form ionic bond.
The formation of ionic bond in this compound can be explained as follows. Note: The electronegativity difference between Mg 1. Note: The bond between Al e. While doing so, both atoms will get the nearest inert gas: Neon's configuration, [He]2s 2 2p 6. Note: The bond between Na e. In general, the bond between two atoms gets ionic nature when the electronegativity difference between them is large greater than 1. Since the Ionic bond is electrostatic force of attraction between cation and anion, the factors favouring their formation also favour the formation of ionic bond.
Hence they lose electrons readily to form cations. Hence these atoms form cation easily. Hence the cations with low charge are formed easily, whereas those with high charge are formed with difficulty. Whereas cations with 18 electrons in outer shell Pseudo inert gas configuration are comparatively less stable and hence are not formed easily.
There are 8 electrons in the outer shell octet configuration Hence it is formed easily. Hence anion with low charge is formed readily. Hence these are hard substances existing as crystalline solids at room temperature.
Their melting and boiling points are very high due to strong electrostatic forces of attractions between the ions. Hence there is no isolated discrete molecule in the ionic crystal.
