Answer» 1 is the answerExplanation:isoelectronic species have same no. of electronshere,K+(Atm. No. 19)loses one e-&Cl-(Atm. No.17) GAIN one e-For completing their octet and to acquirenoble gas configuration which is similar to Argon ( Atomic no. 18)similarly Ca2+(Atm. No. 20) loses two e-and S2- (Atm. No.16) gain to e- |
