Question

which factor contributes to electron shielding in an atom? outer electrons neutron count inner shell electrons atomic radius what unit is typically used to measure ionization energy? kj/mol electron volts calories watts

Explanation:

Electron - shielding in an atom is mainly due to inner - shell electrons that reduce the effective nuclear charge experienced by outer - shell electrons. Ionization energy is the energy required to remove an electron from an atom or ion in the gaseous state, and it is commonly measured in kJ/mol or electron volts. kJ/mol is used in macroscopic chemical contexts while electron volts are used in more atomic - scale and quantum mechanical contexts.

Answer:

1. C. Inner shell electrons
2. A. kJ/mol, B. Electron volts
