Is a Hydrogen Nucleus the Same as a Proton?

I thought that the hydrogen nucleus is just a single proton. So why does this page mention "electorns, protons, hydrogen nuclii", etc?

You must be using the version of IE that has the bug that converts the word Helium to Hydrogen.

If only the bug worked the other way, converting H to He... we'd have a software solution for creating fusion energy.

It says: "electrons, protons, neutrons, helium nuclei..." (Helium, not hydrogen.)

Sorry, I really read that wrong!
