A K* and a CI- ion are separated by 0.52 nm. Find the Coulomb
component of the binding energy at that distance. Give your
answer in electron-volts. (Please include the appropriate sign.) A
positive binding energy would mean the ions are unbound and a
negative binding energy means they are bound.
Note: For this homework problem, round your answer to 2
decimal places.
In this and following questions, we develop a model for spontaneous
emission of a photon by a diatomic molecule AB (a model molecule),
which rotates and vibrates. In intermediate calculations, atomic units
(a.u.) will be used: unit of mass = the mass of electron, unit of charge
is the proton charge e, (e is a positive constant so that the charge of
electron is -e). The initial state of the molecule is an excited
rotational (1=1) and excited vibrational state (v=1). We consider a
molecule with the reduced mass µ = 10,000 a.u. (it is similar to the
mass of CO). After emitting a photon, the molecule will go to the 1=0,
v=0 state. The first question is about the model potential of the
molecule. It is represented by a potential of the form:
V(r)
=
C6
p12
C12
p6
"
where r is the distance between A and B in the molecule, C6 and C12
are positive constants (C6 =2 and C₁2-1). This potential has a well
meaning that the molecule is bound. The first thing to do is find
vibrational states of the…
A sample of copper has a mass of 10.68 g when measured in air. It has a mass of 9.47 g when measured in water.
Answer these three questions:
How many atoms are in the sample?
What is the simple volume of the space including and surrounding each atom? Assume the atoms are evenly distributed throughout the sample. That is no FCC, BCC, or HCP crystal structure.
What is the diameter of each atom?
