a.
the electron moves from a lower energy orbital to a higher energy orbital.
b.
the electron falls into the nucleus.
c.
the electron moves from a higher energy orbital to a lower energy orbital.
d.

Is a logical series of steps

It idk haha what are we doing?

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f. 

Answerit is not a renewable energy source;
