An atom's electron configuration ends with 3p2. If another atom has eight more electrons, what would be the continuation of the electron configuration? 3p24s23d6
3p64s23d2
3p63d24s2
3p23d64s2

They are all full and don't need any more electrons in there outer shell.

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.
