← ScienceWhich outcome results when an energetic alpha particle approaches the inner electron orbitals of a heavy atom?
A)Nuclear recoil leads to ionization✓
B)Electron capture increases atomic number
C)Neutron emission requires more energy
D)Bremsstrahlung radiation excites the nucleus
💡 Explanation
Nuclear recoil leads to high energy electron ionization from inner orbitals by the Rutherford scattering mechanism because it creates direct momentum transfer; therefore energetic alpha causes ionization, rather than electron capture occurring or bremsstrahlung exciting the nucleus.
