Answer to Problem 59QP
Solution: The ion-pairs are
Explanation of Solution
A neutral atom in its ground state cannot be isoelectric with any other element. However, ions may have the same electronic configurations with different atoms or ions.
The electronic configurations of the given elements are as follows:
Electronic configuration for beryllium ion is as follows:
There are total two electrons in beryllium ion.
Electronic configuration for helium atom is as follows:
There are total two electrons in helium atom.
The electronic configurations of
Electronic configuration for fluorine ion is as follows:
There are total 10electrons in fluorine ion.
