What is the best description of the Bohr model of the atom?
a. The atom consists of a positively charged material with negatively charged electrons embedded within it.
b. The atom consists of a nucleus with electrons orbiting randomly around it.
The atom consists of a nucleus with
c. electrons orbiting at specific energy levels. Absorbed photons cause electrons to jump between energy levels.
d. The atom consists of a nucleus surrounded by a region containing electrons. Electrons cannot be located exactly within this region, but the probability that they will be found in an area can be stated.

According to the lab data, the first energy level for Gas B occupies -19 eV of energy. Using the Gizmo, how much energy does the fourth energy level occupy for this same gas?

-2 eV
-8 eV
-11 eV
-13 eV

d
a

I don't agree with a for #1. If it takes 8 eV to make the electron jump from orbit 1 to orbit 2 then the most likely path back is to emit 8 eV to jump back to orbit 1.

I don't agree with d for #2 although that statement is correct. However, I think the Bohr model is best summarized by statement c.

For the last one I have no idea what a Gizmo is in connection to energy levels.

The las one is b- 8eV

Is it possible for my name to get any bigger in literal terms?:'D

To find the energy of the photon emitted when the electron moves back down to energy level 1, we can use the concept of conservation of energy.

The difference in energy between energy level 2 and energy level 1 is 8 eV. Since the electron jumped up to energy level 2 by absorbing a photon of energy 8 eV, the electron would emit a photon with the same energy when it moves back down.

Therefore, the most likely energy of the photon that will be emitted by the electron when it moves back down to energy level 1 is 8 eV.

Answer: 8 ev

The best description of the Bohr model of the atom is option c. According to the Bohr model, the atom consists of a nucleus with electrons orbiting at specific energy levels. Absorbed photons cause electrons to jump between energy levels. This model explains the discrete energy levels observed in atomic spectra.

Answer: c

To find the energy occupied by the fourth energy level for Gas B, we need to compare it to the energy of the first energy level. Given that the first energy level occupies -19 eV, we can determine the energy difference between the first and fourth energy levels.

Using the Gizmo or some other method, if it is determined that the energy of the first energy level is -19 eV, then the energy of the fourth energy level (compared to the first energy level) can be calculated by subtracting the energy of the first level from the energy of the fourth level.

The options provided are in terms of negative energy values, so we need to subtract the energy of the first energy level from the answers to determine the correct option.

Let's calculate:

-2 eV - (-19 eV) = 17 eV
-8 eV - (-19 eV) = 11 eV
-11 eV - (-19 eV) = 8 eV
-13 eV - (-19 eV) = 6 eV

Therefore, the correct option is -8 eV, as -8 eV - (-19 eV) equals 11 eV.

Answer: -8 eV
