Question 13 [time 2 minutes] What would be the interaction energy between two Mg2* ions at...
, Energy of Interaction of Point Charges Coulomb's Law yields an expression for the energy of interaction for a pair of point charges. V is the energy (in J) required to bring the two charges from infinite distance separation to distance r (in nm). Q1 and Q2 are the charges in terms of electrons. (i.e. the constant in the above expression is 2.31×10-19J nm electrons-2) For a group of "point" charges (e.g. ions) the total energy of interaction is the...
The interaction potential between 2 particles that generates the desired effect of particles coming together, sticking, and bouncing off if knocked with sufficient energy is given by the Lennard-Jones (LJ) interaction potential. This potential as a function of distance r between any 2 particles is: U(n) = 4e (9)"-09)) (1) Consider a solution of gold nanoparticles of diameter o = 2 nm. Take e 1 eV. Note that 1 eV = 1.6 x 10-19 Joules. 2. At what distance between...
1) Which of the ions Mg2+, Sr2+, Ca2+, Be2+, Ba2+, or Ra2+ is the largest? 2) Lattice Energy The following compounds all display the NaCl structure. (i.e. They are isomorphous.) For each pair, indicate which would have the lattice energy of greater magnitude. a) CaS or CaSE b) SrO or CaO c) CaO or NaCl d) NaI or LiI e) MgO or CaS *Consider how the relative energies of interaction of "point" charges would vary with respect to the...
The exchange coupling as being responsible for ferromagnetism is not the mutual magnetic interaction between two elementary magnetic dipoles. To show this, calculate (a) the magnitude of the magnetic field a distance of 9.7 nm away, along a dipole axis, from an atom with magnetic dipole moment 2.0 × 10-23 J/T, and (b) the minimum energy required to turn a second identical dipole end for end in this field.
