core electron meaning in Hindi

Examples

1. For zinc, the 3d subshell is complete and behaves similarly to core electrons.
2. Non-resonant excitation occurs when the incoming radiation promotes a core electron to the continuum.
3. Pseudopotentials replace the atomic nucleus and the core electrons by an effective numeric potential.
4. In resonant excitation, the core electron is promoted to a bound state in the conduction band.
5. The excitation of core electrons is possible, but requires much higher energies, generally corresponding to x-ray photons.
6. A core electron can be removed from its core-level upon absorption of electromagnetic radiation ( X-ray ).
7. This is followed by a cascade of electron relaxation as the core electron hole moves toward the valence orbitals.
8. The resulting atom will have an empty space in the core electron shell, often referred to as a core-hole.
9. The effect always competes with a diamagnetic response of opposite sign due to all the core electrons of the atoms.
10. If a core electron is missing, a positive ion can autoionize further and lose a second electron in the Auger effect.
