← ScienceWhich outcome occurs when potassium's 4s orbital empties?
A)Increased spin polarization of surface
B)Enhanced electrical conductivity declines linearly
C)Reduced atomic radius and ionization✓
D)Diamagnetic susceptibility becomes more positive
💡 Explanation
The atomic radius decreases because effective nuclear charge increases; therefore, ionization energy rises sharply, rather than altering spin or bulk conductivity. The mechanism is electron shielding; reduced shielding from the 4s orbital leads to tighter binding.
