Question

(6 pts) For each of the following statements, indicate whether it fits best with Bohr model of the atom, the quantum mechanical model of the atom, both, or neither.
A) Accounts for the interactions between electrons
B) Does not work for atoms/ions with more than one electron.
C) The energy of electrons are quantized.
D) Electron locations are related to wavefunctions.
E) The model is probability based.
F) Electrons orbit the nucleus like planets.

Answer 1

A) Accounts for the interactions between electrons (quantum mechanical model of the atom)

Explanation:

Bohr's atomic model explains energy of electron, radius of orbits, excitation and absorption of energy of electron. But doesnot explain the interaction between electrons.

Quantum explain the spin of the electron which explains interaction of electrons (Spin quantum number: electrons in same orbital have opposite spins)

B)  Does not work for atoms/ions with more than one electron. (Bohr model of the atom)

Explanation:

Bohr's model explains only for single electron species.

Quantum model is applicable for single and multi electron species.

C) The energy of electrons are quantized. (quantum mechanical model of the atom)

Explanation:

According to Bohr's atomic model the path of the electron are called statioary orbits or energy states. The electron emits energy(not quantized) when it jumps from higher energy level to low energy level.

According Quantum mechanic model the energy of electrons are quantized.

D) Electron locations are related to wavefunctions. (quantum mechanical model of the atom)

Quantum mechanic model used wave functions.

E) The model is probability based. (quantum mechanical model of the atom)

Bohr's model of atom is like planets revolving around the sun in particular path.

Quantum mechanic model used wave function and probability of finding electron.

F) Electrons orbit the nucleus like planets. (Bohr model of the atom)

As explained above (E) for Bohr's model
