1. If the principal quantum number of a shell is equal to 2, what type(s) of orbitals will be present? a) s b) s and p c) s, p, and d d) s, p, d, and f Ans: b) 2. The Pauli exclusion principle states that a) no two electrons can have the same four quantum numbers b) it is impossible to simultaneously determine the momentum and the position of an electron c) energy is emitted from matter as quantized units d) an electron will enter an empty orbital as a subshell before entering half- filled orbitals e) electrons travel around the nucleus in orbits of known radii Ans: a) 3. The total number of electrons that could be held in a sublevel with angular momentum number equal to 2 is a) 2

Unformatted text preview: b) 6 c) 8 d) 10 Ans: d) 4. Your I-clickers transmit at a frequency of 915 MHz. a) Suppose that your seat is 40ft from the receiver. Express this distance in clicker wavelengths. b) Suppose a electron in a hydrogen atom has the absurdly high energy of 2.690 x 10-22 J. Could this atom absorb photons from your clicker? Justify your answer with a numerical calculation. 5. An ion has a single electron. The longest wavelength of radiation absorbed by this ion in its lowest energy state is 7.60 nm. A) Which ion is this? b) What is the minimum energy (in J) required to complete this electron from the ion in its lowest energy state?...
