(a)At the equilibrium position when the distance between to ions? = ?0, the force of Coulombic attraction, ?? and the repulsive force ?? cancel each other, and the bond behaves like a spring. What is the important consequence of this behavior? (b) What causes the repulsive force ?? ? (c) Why is the radius of a ??1+-ion is less than that of ??-atom?
Please answer 2,3,4 2. How many platinum (Pt) atoms are in a cube that is I mm on each side? What is the average volume occupied by each atom? (Divide the total volume by the number of atoms in the volume.) 3. What is the side of a cube holding exactly 1 mol of gold (Au) atoms? Assume that the equilibrium separation distance of the ions in sodium fluoride (NaF) is the sum of the Na and F ionic radii....
In a magnesium oxide unit, the distance between the magnesium ion (Mg2+) and the oxide ion (O2−) is 2.07×10-10 m. Calculate the work required to separate the two ions to an infinite distance apart. (Model the ions as point charges at rest before and after the separation.)
In a magnesium oxide unit, the distance between the magnesium ion (Mg2+) and the oxide ion (O2−) is 1.81×10-10 m. Calculate the work required to separate the two ions to an infinite distance apart. (Model the ions as point charges at rest before and after the separation.)
In a magnesium oxide unit, the distance between the magnesium ion (Mg2+) and the oxide ion (O2−) is 2.13×10-10 m. Calculate the work required to separate the two ions to an infinite distance apart. (Model the ions as point charges at rest before and after the separation.) If you could do this without using Calculus that would be great.

The separation between the oxygen and carbon atoms in a carbon molecule is 0.113 nm. Assume the charges are +1.0e and -1.0e. a) Find the electric dipole moment of the CO molecule. b) We immerse the molecule into a uniform electric field of strength 2.0 x 105 N/C and oriented such that the electric dipole moment is making an angle of 53 degrees with respect to the field. What is the net torque in the molecule around its center of...
How would the force of gravity between two masses be affected if the separation distance between them were the following? (Assume F2 represents the new force and F1 represents the original force.) (a) double the original distance (b) one-fifth the original distance
The potential energy of two atoms in a diatomic molecule is approximated by U(r)=d/r12-b/r6, where r is the spacing between atoms and a and b are positive constants. Find the force F(r) on one atom as a function of r. Find the equilibrium distance between the two atoms. Express your answer in terms of the variables a and b. Is this equilibrium stable? Suppose the distance between the two atoms is equal to the equilibrium distance found in part (b)....
