Q1. Select the species which are iso-electronic (same number of electron) with each other.
Answer : Option A
Explaination / Solution:
Neutral Cl ( Z=17) has 17 electrons and with the addition of one more electron it becomes Cl- anion which has 18 electrons.
Neutral Ca (Z=20) has 20 electron and with the removal of 2 electrons it becomes Ca2+ cation which has 18 electrons.
Since Cl- and Ca2+ both has 18 electrons , so they are isoelectronic.
