Thank you for the opportunity to help you with your question!

The Helium atom in its neutral state has 2 protons, 2 electrons and most of the time 2 neutrons.  I would agree if the ionized state was  He 2+, not He 5+.  Since if Helium were positively charged with 5+ you would have 5 protons and no electrons.  But this would contradict Helium's atomic number of 2.  I think the problem meant He 2+ instead of He 5+, otherwise you would have Boron 5+ with no electrons.

Corrected Version:#Electrons:  0,  # of Protons: 2 Charge +2, #of neutrons: 2, Atomic # 2, Symbol: He 2+


Please let me know if you need any clarification. I'm always happy to answer your questions.

It is possible that there exist positive charge particles with the same size as electrons called positrons.  It may be possible that the helium ion could contain 2 protons, 2 neutrons and 3 positrons. That means in the red mark off we put  -3 electrons.
