Five cards from this deck

Taken from the published archive, unedited. A deck page that shows no card says nothing.

  • Front amplitude
    Back extent of the displacement caused by a wave (for sinusoidal waves, it is one-half the difference from the peak height to the trough depth, and the intensity is proportional to the square of the amplitude)
  • Front angular momentum quantum number (l)
    Back quantum number distinguishing the different shapes of orbitals; it is also a measure of the orbital angular momentum
  • Front atomic orbital
    Back mathematical function that describes the behavior of an electron in an atom (also called the wavefunction), it can be used to find the probability of locating an electron in a specific region around the nucleus, as well as other dynamical variables
  • Front Aufbau principle
    Back procedure in which the electron configuration of the elements is determined by “building” them in order of atomic numbers, adding one proton to the nucleus and one electron to the proper subshell at a time
  • Front blackbody
    Back idealized perfect absorber of all incident electromagnetic radiation; such bodies emit electromagnetic radiation in characteristic continuous spectra called blackbody radiation

Updated on

This deck was modified when it was brought in: Entries were taken from the end-of-chapter glossaries of chapters 6 and gathered into one deck; the chapter structure of the book is not reproduced. HTML formatting was stripped to plain text, and superscripts and subscripts were converted to the corresponding Unicode characters so that a charge or an index is not lost (H⁺, not H+; T₄, not T4). An entry was dropped when its definition is shorter than 30 characters or longer than 400 characters, when it contains an image, a table or a mathematical formula that is not reproduced here, when it refers to a figure, a table or another chapter, when it is dated by wording such as "currently" or "as of", when it is a bare cross-reference to another term, or when a superscript could not be converted faithfully. Duplicates were removed on the term and on the definition alike, both compared after lowercasing, removing parentheses and reducing plurals to singulars; a term or a definition already used by another Memoquiz deck built from OpenStax was dropped as well. Each deck is capped at 150 entries and holds at least 30. The wording of every definition that was kept is unchanged.
