Why is Helium bigger than Hydrogen
With an increase in nuclear charge and no increase in the number of electron shells, the atomic radius should decrease as the greater nuclear charge
pulls the electrons closer together. Why then, is Helium bigger than Hydrogen?

Sorry, I think the data given in my book is wrong. Looked up on the net and it looks like Hydrogen is actually bigger. Sorry about that
