my answer is:
E=hc/λ so E= 6.63e-34 x 3.0e8 /λ = 1.989e-25/λ
Eorbital1-Eorbital0=7.84e-19 J
Eorbital2-Eorbital0=1.08e-18 J
Eorbital3-Eorbital0=1.25e-18 J
Eionisation= 1.66 × 10-18J... we make this zero and compare how much energy it would take to get an electron to this energy
Eorbital1 -...
i only joined to answer a question and now I've joined i find the thread is closed :-(
the question was:
An element has an ionization energy of 1.66 × 10-18 J. The three longest wavelengths in its absorption spectrum are 253.7 nm, 185.0 nm and 158.5 nm. Construct an energy-level diagram for...
