Give examples of species isoelectronic with  Ca²⁺   ???

K⁺ , Cl^- , S^2- , Sc ³⁺ , Ar are some examples of isoelectronic species with Ca ²⁺

Ar , K ⁺ , Cl ^- ,  S^{2 -}  ,  P ^{3 -} ,  Si ^{4 -} etc. There are many more examples.

Thanks Angel..........

Thanks Shika

But it would be more appreciable if u can tell me, how to find isoelectronic species ???

coz i could not clear my doubt about finding isoelectronic species with any element, as Ca ^2+.....

Plzzzz reply today itself ( if possible ).......

Plzzzzz reply with the appropriate method or concept or whatever, to find isoelectronic species with anty element.....

Okkkkk......

Thank You....

oh sorry yar i didn't reply u yesterday..  iso elcetronic species mean ions  or element having same electronic cong. to know isoelectronic species 1st u have to know the electronic configuration of an element. for eg: Ca has electronic confg. 2,8,8,2. then Ca 2+ hav electronic confg. 2,8,8 ie, subtracting the charge from its electronic cong if its a + signand if its a - sign add the charge. for eg :  Cl has electronic confg. 2,8,7. Cl- has electronic confg. 2,8,8, ie, add the charge. i hope u understood.
