12 multiple choice 1 point the phenomenon in which full inner electron shells prevent valer nuclear charge shielding effect ionization energy reactivity
Answer
Brief Explanations:
The shielding effect occurs when full inner - electron shells reduce the effective nuclear charge experienced by valence electrons by blocking the attraction between the nucleus and valence electrons.
Answer:
B. shielding effect
