Pick one option:
Dmitry [639]

Answer:

Li⁺

Explanation:

Li⁺ ions has a noble gas electron configuration because it resembles that of He.

To have a noble configuration, electrons in the outermost shell must completely fill their respective orbitals.

Li⁺ is an ion that has lost one electron from the usual number of 3 thereby remaining 2 electrons.

 The electronic configuration is given as;

         Li⁺       1s²

The S orbital can hold a maximum number of just two electrons.

     Helium atom has two electrons with electronic configuration of  1s²

Therefore      Li⁺   =    1s²    =    He
