|Angular momentum quantum number
||(also known as the azimuthal quantum number.) The quantum number
that distinguishes orbitals of given n having different shapes; it can
have any integer value from 0 to n - 1.
|Atomic number (Z)
||the number of protons in the nucleus.
||a wave function for an electron in an atom; pictured qualitatively by
describing the region of space where there is a high probability of
finding the electron.
|| a very light particle that carries a unit
negative charge and exists in the region around the
positively charge nucleus.
||the energy change for the process of adding an electron to a neutral
atom in the gaseous state to form a negative ion
||the particular distribution of electrons among available subshells
|Group (of the periodic table)
||the elements in any one column of the periodic table
||the energy needed to remove an electron from an atom (or molecule)
|Magnetic quantum number (ml)
||the quantum number that distinguishes orbitals of given n and 1-that
of given energy and shape-but having a different orientation in space; the
allowed values are the integers from -1 to +1
|| a substance or mixture that has a characteristic luster,
or shine, is generally a good conductor of heat and electricity, and
is malleable and ductile.
||an element that does not exhibit the characteristics of a metal
|Period (of the periodic table)
||the elements in any one horizontal row of the periodic table
||a law stating that when the elements are arranged by atomic number,
their physical and chemical properties vary periodically
||a tabular arrangement of elements in rows and columns, highlighting
the regular repetition of properties of the elements
|Principal quantum number (n)
||the quantum number on which the energy of an electron in an atom
principally depends; it can have any positive value: 1, 2, 3, etc.
|Spin quantum number (m,)
||the quantum number that refers to the two possible orientations of
the spin axis of an electron; possible values are +1/2 and -1/2
