Bohr Model
Multiple Choice
What is the main difference between the Schrödinger model and the Bohr atomic model?
A
The Bohr model describes electrons in fixed circular orbits, while the Schrödinger model describes electrons as probability clouds (orbitals).
B
The Bohr model allows for electron spin, while the Schrödinger model does not.
C
The Schrödinger model only applies to hydrogen atoms, while the Bohr model applies to all elements.
D
The Bohr model uses quantum numbers, while the Schrödinger model does not.
검증된 단계별 안내1
Step 1: Understand the Bohr atomic model - it describes electrons as particles moving in fixed, circular orbits around the nucleus with quantized energy levels.
Step 2: Understand the Schrödinger model - it treats electrons as wave-like entities described by a wavefunction, which gives a probability distribution of where an electron is likely to be found, called orbitals.
Step 3: Compare the electron description - Bohr's model uses fixed paths (orbits), while Schrödinger's model uses probability clouds (orbitals) to represent electron positions.
Step 4: Recognize that the Schrödinger model is more general and accurate, applying quantum mechanics principles to describe electron behavior beyond hydrogen atoms.
Step 5: Conclude that the main difference lies in the conceptualization of electron location: fixed orbits in Bohr's model versus probabilistic orbitals in Schrödinger's model.
