An atmospheric physicist is investigating the ionization and excitation of nitrogen atoms in the upper atmosphere when exposed to extreme ultraviolet (EUV) radiation.
State two possible outcomes for a bound orbital electron in a nitrogen atom when it absorbs an EUV photon.
A student proposes that the subsequent transition of an electron to fill any vacancy created in part (a) could result in the emission of a beta-plus (β+\beta^+β+) particle.
Explain why the student's proposal is incorrect.
