Given the information above, the element that emits the lowest energy photon of visible light is: 7. O copper O strontium O barium O sodium 8. The colours are emitted by electrons that are: O emitted by the nucleus

A hypothetical atom has energy levels given in the figure below. Which figure most accurately depicts the absorption spectrum, assuming all transitions between energy levels is possible? The black vertical lines represent the absorbed wavelengths. Eo = -11.5 eV E₁ = -9.6 eV E₂ = -5.2 eV O E3 = -1.1 eV wavelength increases → wavelength increases → wavelength increases → wavelength increases → wavelength increases →

2. Below are the energies of the first 6 energy levels in Lithium as well as the energies of 6 photons. How many of the photons can be created by an electron that transitions between the any two of the first 6 energy levels in Lithium?
