Which of the following concepts underlies all the others: ionization energy, effective nuclear charge, atomic size.
A)ionization energy
B)effective nuclear charge
C)atomic size
D)none of the above

Question

Quizplus · Accepted Answer

Effective nuclear charge (Zeff) refers to the net positive charge experienced by an electron in a multi-electron atom. It is determined by the number of protons in the nucleus minus the number of shielding electrons. Ionization energy and atomic size are both affected by Zeff, which makes it the concept that underlies all the others.
