10.2 In Figure P10.2, identify the physical state(solid, gas, or gas) of xenon and classify the attractive forces between the xenon atoms.
I know it is a solid in the image just dont know how to explain the second part of the question. Thank you in advance!
Homework Answers
In the image, the particles are arranged in a hexagonal close pack structure. This kind of structuring can only take place in a solid system. Hence xenon is in solid state in the image.
Between atoms and molecules, different kinds of interactions are observed. One of the interactions that is found in case of nonpolar systems is known as London dispersion forces. It is a weak kind of interactions that arises when the electrons are arranged unsymetrically in the atoms or molecules. In such cases, an instantaneous attraction takes place between the oppositely oriented dipoles. Because of such interactions, the nonpolar atoms or molecules can form liquids or solid at lower temperature.
Here because of this London dispersion force between the atoms, the xenon atoms form solid structure as shown in the image.

EENG 245 Physical electronics HW 1 1) The NaCl crystal is cubic, and can be described as follows. Na atoms sit at the corners and faces of a cube, and Cl atoms sit in between two Na atoms. This means that a Clatom is found half-way along each of the cube edges, and there is a Cl in the center of the cube. (We could also have described the lattice by interchanging Na and Cl in the description above.) Another...

Please answer the following question below based on the information
and figure. I just need a description of which bulb will go
brighter in each of the pictures. And any equations that would be
necessary to explain this. It does not need to be worked out with
numbers. Just the equations and words explaining how you can tell
which glows brighter. Thanks! Below is also an example of how to
set it up!
