MCQ
Favourable conditions for electrovalency are
  • Low charge on ions, large cation, small anion
  • B
    High charge on ions, small cation, large anion
  • C
    High charge on ions, large cation, small anion
  • D
    Low charge on ions, small cation, large anion

Answer

Correct option: A.
Low charge on ions, large cation, small anion
a
Electrovalency is calculated for ionic compounds. Greater the size of metal atom, easier is the formation of cation. Smaller the size of the non-metal, easier is the formation of the anion.

Lower charge is another favourable factor in the formation of ionic compounds. It is easier to remove smaller number of electrons to form a positively charged cation as a lesser amount of ionization energy has to be supplied. Same is the case for anion formation.
