a. The energy requirements of a given arrangement of atoms
b. hund’s rule
c. pauli exclusion principle
d. Heisenberg uncertainty principle

There are three p orbitals that are aligned with their major axes along the x, y, and z axes, what is the origin of these three p orbitals?
a. They are the solutions for the three values of the magnetic quantum number.
b. They result from hybridization with three different s orbitals.
c. The p orbitals are always three-dimensional.
d. They result from three different energy levels.

A metal begins to emit electrons, as measured in an apparatus similar to the one Hertz used, when exposed to light at a wavelength of 342 nm (ultraviolet). What is the work function of this metal?
a. 4.96 × 1019 J
b. 9.50 × 1019 J
c. 3.63 eV
d. 1.95 eV

Explanation / Answer

Of the following the one which does not concern the placement of electrons in an atom,

d. Pauli's exclusion principle

The origin of the three p-orbitals aligned along the x, y, and z axis would be,

a. They are the solutions for the three values of the magnetic quantum number.

The work function of the metal would be,

c. 3.63 eV

work function = hc/l = 6.626 x 10^-34 x 6.242 x 10^18/3 x 10^8 x 342 x 10^-9 = 3.63 eV
