So I've been trying to figure these out for awhile, not sure where I'm going wrong in solving it but it's coming out wrong constantly for me, help would be majorly appreciated!
1. If a molecule having an ionization energy of 9.03 eV produces a photoelectron having a kinetic energy of 6.85656E-19 J, what is the wavelength of the incident radiation? Solve in nm
2. When LCAO molecular orbitals of methane (CH4) are formed from the carbon 2s and 2p atomic orbitals along with the 1s orbitals on the H atoms, what is the total number of molecular orbitals that are formed in this process?
