Share:
- 1The valence shell expands outward to establish a completely continuous macroscopic spectrum
- 2The electrical charge of the core protons alters from positive to neutral values
- 3The electron mass increases infinitely, preventing any spatial displacement or orbit changes
- 4The physical space available to conduction electrons restricts, leading to quantized energy states✓
Correct answer
The physical space available to conduction electrons restricts, leading to quantized energy states
