Here is a sketch of a 2px orbital: this sketch is about 800pm wide. the coordinate ( x , y , and z ) axes are also shown. you can rotate the sketch for a better view of the orbital by dragging the slider with your mouse. suppose an atom with its nucleus at the origin has an electron in a 2px orbital. complete each row of the table below by deciding how pa , the probability of finding the electron at point a , compares to pb , the probability of finding the electron at point b . point apoint bcompare pa to pb 100 pm to the left of the nucleus, along the -x axis. 100 pm below the nucleus along the -z axis. papb 100 pm in front of the nucleus, along the -y axis. 100 pm behind the nucleus, along the +y axis. papb 100 pm to the right of the nucleus, along the +x axis. 100 pm above the nucleus, along the +z axis. papb
