- This question relates to energy levels in the hydrogen atoms.
- Calculate the energy change when an electron is promoted from the n = 2 to the n = 9 level in a hydrogen atoms
- This question relates to energy levels in the hydrogen atoms.
-
- If the electron falls back from the n = 9 to the n = 2 level, calculate the wavelength of light corresponding to this transition.
-
- If the range of visible light is from 400nm to 750nm, in which region of the electromagnetic spectrum will this emitted light be located?
-
- If the electron in a hydrogen atom is moved from the n = 2 to the n = ∞ (infinity) energy level, why does the associated energy change NOT equal the ionization energy of the hydrogen atom?

The sun is mostly composed of hydrogen-1 atoms.
When two of these hydrogen-1 atoms collide, it produces no nuclear
reaction. Why?
And
How does the collision between two hydrogen-1 atoms in the sun
become a nuclear fusion reaction?

Calculate the energy (J) of the photon emitted when an electron
in the hydrogen atom falls from n=5 to n=2 .
Use 2.178 x 10-18 J for the constant in the Bohr
equation.
Answer should be in scientific notation, e.g.
3000 = 3E3
