How far from the nucleus in angstroms (1 angstrom = 1 10–10 m) is the electron in a hydrogen atom if it has an energy of –8.7210–20 J? The radius of the orbital (r) = n2 a0/Z (n is the quantum number of an orbital, a0 is the Bohr radius with a value of 5.292×10−11 m, Z is the nuclear charge). Hint: figure out n first and the radius of the orbital is the distance.
