A doubly-ionized lithium atom Li++, which has 3 protons, undergoes a transition from the n = 5 state to the n = 4 state.

What is the wavelength of the photon which is emitted during this transition? (c = 3.00 108 m/s, h = 6.626 10-34 J s, 1 eV = 1.60 10-19 J)
A) 650 nm B) 550 nm C) 450 nm D) 350 nm E) 750 nm

Question 2

What is the ground state energy of the Li++ ion, which has atomic number 3?

A) -61 eV
B) -40.8 eV
C) -1.51 eV
D) -122 eV
E) Li++ does not have a ground state.
