Questions

  1. 1.

    How does the quantum mechanical model describe the behavior and spatial distribution of electrons around the atomic nucleus?

    • A) Electrons move along fixed, concentric circular paths where their exact positions and velocities can be determined simultaneously.
    • B) Electrons are embedded statically throughout a continuous sphere of positive charge to maintain electrostatic stability.
    • C) Electrons occupy three-dimensional regions of space called orbitals, which represent probability distributions of finding an electron rather than definite paths.
    • D) Electrons radiate electromagnetic energy continuously as they spiral toward and eventually collide with the positively charged nucleus.
