Question

The energy levels the electron can occupy in the H atom can be calculated using the energy level equation. A H atom with an electron in the n= 3.00 level emitted a photon with a wavelength of 656 nm. What is the value of the level n for the new energy?

Answer 1

Answer:

n₂ = 2.00

Explanation:

Using the Rydberg Energy Equation of 1/λ = R * Z² * (1/n₂² - 1/n₁²)

this is where λ is the wavelength, z is atomic number, n₁ is the initial energy level, n₂ the final energy level and R is the Rydberg constant with a value of ≈ 1.0973 * 10^7 1/m.

If we plug all the given numbers in the the equation we are left with an unknown of n₂, solve for n₂ and your answer will be 2.00
