Chemistry
Answer
The conditions for the formation of an electrovalent bond are:
- Low ionisation potential — If the ionisation potential of a particular atom is low, it will lose electron(s) easily, i.e., a cation is formed easily.
- High electron affinity — If the electron affinity value is high, anion will be formed easily.
- Large electronegativity difference — If the difference in the electronegativities of two elements is higher, then the transfer of electrons will be easier.
