Help with a review question please! Test tomorrow
Can you please help with this review question. My test is tomorrow and I am not sure how to do this.
Helium cation behaves like hydrogen atom. A particle with kinetic energy of 90.00 x 10^-12 erg collides with a gaseous helium cation in its ground state, quantum level n=1. After the collision, the kinetic energy of the particle is found to be 8.262 x 10^-12 erg. This event is followed by the Helium ion with the electron in quantum level n=? emitting light with a wavelength of 1214 angstroms when the electron drops to the quantum level n = 2. What is the energy of the electron in the ground electronic state, E1 of the helium atom?
