Chemical Bonding And Molecular Structure Question 125
Question: In the transition of $ Zn $ atoms to $ Z{n^{++}} $ ions there is a decrease in the [CPMT 1972]
Options:
A) Number of valency electrons
B) Atomic weight
C) Atomic number
D) Equivalent weight
Show Answer
Answer:
Correct Answer: A
Solution:
Ion is formed by gaining or losing electrons. To form cation electron are lost from the valency shell, so Zn atoms to $ Z{n^{++}} $ ions there is a decrease in the no. of valency electron.
