CHEM 210 Exam 1 - Biochemistry | Exam Questions & Verified Answers
wavelength The distance between two corresponding parts of a wave
Frequency number of waves per second
electromagnetic radiation Gamma rays > X-rays > ultraviolet > visible light > infra-red > Microwaves > radio
waves
continuous spectrum when you separate white light into its components with a prism, you obtain a
continuous spectrum
line spectrum when you separate the light emitted by atoms in the gas phase, you obtain a line
spectrum
how is a line spectrum produced when the electron moves to a lower energy level
Emission vs. Absorption emission: release of light/energy
absorption: gain of light/energy
principle quantum number (n) describes the size of the orbital

angular momentum quantum number (l) indicates the shape of the orbital
each angular momentum letter and number s-1
p-3
d-5
f-7
magnetic quantum number (m sub l) describes the orientation of the orbital
electron spin (m sub s) describes the direction of the spin of an electron
Pauli Exclusion Principle (2) 1. no two electrons in an atom can have the same four quantum numbers
2. As there are only two possible values for m(s)
Aufbau principle states that an electrons are added to the lowest energy orbitals first before moving
to higher energy orbitals
electron configuration the arrangement of electrons in an atom (picture is important)
orbital diagrams pictorial representations of the electron config.
Hund's rule electrons enter unoccupied orbitals first before pairing
