1.Which of the scenarios presented below is linked to Hund'srule?
a. Arsenic has 3 unpaired electrons in its 4p subshell.
b. If two electrons share an orbital, they must have oppositespin.
c. The 4s subshell will be filled with electrons before the 3dsubshell.
d. An electron can act like a wave or a particle, but not at thesame time.
2. Why is the principle quantum number, n, alwaysa whole number?
a. The principle quantum number, n, represents theenergy level of the electron.
b. The n value indicates the number of wave cycles theelectron wave completes in a circular orbit. A non-integer valuewould result in destructive interference.
c. Because the wavelengths of light that are calculated for theatomic emission spectrum of hydrogen only match the experimentalvalues when n is assigned a whole number.
d. The principle quantum number, n, represents the electron'sorbit number.
