What is electropositive character? Why alkali metals form only monovalent ions?
Asked by Topperlearning User | 12 Aug, 2014, 01:43: PM
Expert Answer
The electropositive character of an element is expressed in terms of the tendency of its atom to release electrons:
All the alkali metals are strongly electropositive or metallic in character, since they have low ionization energies and their atoms readily lose the valence electron. As the ionization energies decrease down the family, the electron releasing tendency or electropositive character is expected to increase down the family.
