← ScienceWhich outcome occurs when a high-energy electron excites an atom?
A)Auger electron emission occurs spontaneously✓
B)Photoelectric effect increases substantially
C)Resonance enables nuclear transmutations
D)Superconductivity emerges at lower temperatures
💡 Explanation
Auger electron emission releases core electrons affected by inner shell ionization; because during **relaxation**, excited electron creates a vacancy cascade and ejects additional (Auger) electrons off the atom’s orbital cloud; therefore Auger process, rather than photoelectric effect or altered resonance, initiates
