The electron configurations of five different elements are shown below. Which of these elements is expected to have the largest second ionization energy (IE2)?

Radial probability densities (probability plots) can be used to illustrate the probability of electron location outside the nucleus of an atom. What is the term associated with the spot where this probability goes to zero?

Which of the following forms of EM Radiation has the lowest frequency?

What is the hybridization of the carbon atom notated with an arrow in the molecule shown below? (Note that lone pairs have been omitted for clarity… and because I’m lazy)

Consider the following probability functions for the 1s, 2s and 3s orbitals: Which of these statements is false?

Many varieties of scorpions glow (through a process called fluorescence) when exposed to UV light around 365 nm. What is the frequency of 365 nm UV light?

What mass of AgBr is formed when 57.8 mL of 0.423 M AgNO3 reacts with an excess of aqueous hydrobromic acid (HBr)? (Hint: You’ll want to start by writing a balanced equation for the process)

What is the frequency (in Hz) of a photon that has an energy of 4.38 x 10-18 J?

The electrical conductivities of the following 0.100 M solutions were measured with Jim’s light bulb conductivity apparatus: HF, KI, CH3OH, Al(NO3)3.  Rank these solutions in order of decreasing intensity (brightest to dimmest) of the light bulb:
