QUESTION 1

Which of the following ideas related to the Bohr model of the atom do we no longer like?

electrons orbit the nucleus at specific distances

electrons can transition between energy states by absorbing or releasing energy

electrons occupy specific energy states within an atom

QUESTION 2

According to the idea of wave particle duality, which of the following items has a wavelength? Choose all that apply.

An electron moving at 2.80 m/s.

A planet moving at 180,000 km/hr.

A person running at 10 mi/hr.

A gas molecule moving at 515 m/s

QUESTION 3

electrons orbit the nucleus at specific distances

electrons can transition between energy states by absorbing or releasing energy

electrons occupy specific energy states within an atom

Explanation / Answer

1-The Bohr Model considers electrons to have both a known radius and orbit, which is impossible according to Heisenberg. so option a is correct

2-The property of particles behaving as waves and the property of waves behaving as particles as well as waves. Although the duality is not very effective in large matter. The wave characteristic of the electron implicates many of the electron's particle behaviors.

so it would a tiny object with a optimum speed , so option a is correct.

3-wavelength=h/mv

=6.634*10^(-34)/9.1*10^(-31)*5.75*10^(7)=0.126 nm
