The 2px and 2py orbitals in an H atom are degenerate.
This is referring to Hund's Rule...already been to wiki and all that...i need to know if this is true or false and why...i'm lost!

This is true. The Px, Py, and Pz orbitals are degenerate in all atoms provided the atom is not subjected to a magnetic field.
In hydrogen and other single electron systems (He+ etc) only the n quantum number matters to determine energy. So you can actually say that the 2s, 2px, 2py and 2pz are all degenerate.
The s, p etc orbitals lose this degeneracy when there is more than one electron due to electrostatic repulsion between the electrons, so then you need both the n quantum number and the l quantum number to determine energy.

Degenerate orbitals are of the same energy (different wavefunctions with the same energy level).
The 2px and 2py and 2pz atomic orbitals of hydrogen have the same energy and are thus degenerate.
Look up Rydberg constant and Schrodinger equation for the hydrogen atom.
