Multiple Choice

What is the most current atomic model?

Multiple Choice

What is the quantum mechanical model of the atom and how does it differ from Bohr's model?

• The quantum mechanical model considers electrons as having both particle-like and wave-like properties, represented by probability distributions called orbitals, allowing for more accurate predictions compared to Bohr's model.

• The quantum mechanical model only considers electrons as particles, ignoring their wave-like properties.

• The quantum mechanical model uses circular orbits for electrons, similar to Bohr's model.

• The quantum mechanical model predicts electron positions with absolute certainty, unlike the probabilistic nature of Bohr's model.
