Chemistry help! An atom X, has aground state binding energy state of (2.179*10^-18)J .?



Line spectrum: Left to Right: 121.57 nm, 102.57nm,97.254nm, 94.974nm,93.780nm.
A. can atom X emit light of energy 3.03*10^-19J? If so what are the initial and final states of such transition.
B. Is it possible for X to absorb light energy of 2.5*10-18J? why or why not
