Yes, the correct answer is d) 4s.
In many-electron atoms, the effective nuclear charge experienced by an electron depends on its energy level and subshell. The effective nuclear charge increases across a period in the periodic table, meaning that the electrons in the inner shells shield the outer electrons from the full positive charge of the nucleus.
The 4s subshell is closer to the nucleus than the other subshells listed in the options, so the effective nuclear charge experienced by the electron in the 4s subshell is the greatest. Therefore, the electron in the 4s subshell experiences the greatest effective nuclear charge in a many-electron atom.
An electron in a(n) __________ subshell experiences the greatest effective nuclear charge in a many-electron atom. Question 18 options:
