Lithium adopts a BCC structure at room temperature with a lattice parameter equal to 3.51 Å. ...

Lithium adopts a BCC structure at room temperature with a lattice parameter equal to 3.51 Å. a).Find the Li-Li pairs corresponds to the 3 shortest distances. Assume the correlation is between a Li at (x,y,z) and the Li at the origin, i.e. (0, 0, 0). For example, the shortest Li-Li pair (also known as Li-Li correlation) is given by the Li at (0,0,0) and the Li at (0.5, 0.5, 0.5). Your answer should only show the cooridinates of the Li...

Design and implement a function which has one input parameter which is a number which is greater than 50, called num. Then the function will create a dictionary whose keys are 2 and 3 and 4 and 5 and 6 and 7 and 8 and 9. Then the function calculates the values for each of the above keys. The value for a key is all the numbers between 2 and input “num” that are divisible by the key. The function...
