In the transition of Zn atoms to Zn++ ions there is a decrease in the [CPMT 1972] (a) Number of valency electrons (b) Atomic weight (c) Atomic number (d) Equivalent weight
Correct option is A) Ion is formed by gaining or losing electrons. To form cation electrons are lost from the valence shell, so Zn atoms to Zn + + ions there is a decreases in the no. of valency electron.
