Question

Difference between :

Monovalent Electropositive ions & Monovalent Electro - -negetive ions . ​

Answer 1

Explanation:

Formation of Electropositive ions

Monovalent

Potassium atom loses one electron from its outermost (valence) shell to form univalent or monovalent positive ion. Here, univalent or monovalent means having the valency one.

          K     -    e-   →   K1+

     Unstable             Stable 

    potassium         potassium

       atom                   ion

Divalent 

Magnesium atom loses two electrons from its outermost (valence) shell to form divalent positive ion. Here, divalent means having the valency two.

         Mg    -  2 e-  →    Mg2+

     Unstable               Stable 

    magnesium        magnesium

       atom                   ion

 

 

 

Trivalent

Aluminium atom loses three electrons from its outermost (valence) shell to form trivalent positive ion. Here, trivalent means having the valency three.

 

          Al   -  3 e-  →      Al3+

     Unstable               Stable 

    aluminium           aluminium

       atom                     ion

Answer 2

Answer:

electropositive = the ability of as atom to loose and double it's election

electronic negative = the frequency to gain an election.
