  • Condensed Electron Configuration
    A shorthand notation for electron arrangements using the symbol of the previous noble gas followed by remaining subshells.
  • Electron Arrangement
    The specific distribution of electrons among atomic orbitals for an element or ion.
  • Noble Gas
    An element from Group 18 used as a reference point in shorthand electron configurations.
  • Periodic Table
    A tabular display organizing elements by atomic number and electron configuration blocks.
  • s Block
    A region on the periodic table where elements have their outermost electrons in an s orbital.
  • p Block
    A section of the periodic table where the highest-energy electrons occupy a p orbital.
  • d Block
    A group of elements whose valence electrons fill d orbitals, often called transition metals.
  • f Block
    A set of elements where electrons fill f orbitals, typically shown separately at the bottom of the table.
  • Element
    A pure substance consisting of atoms with the same number of protons, identified on the periodic table.
  • Ion
    An atom or molecule with a net electric charge due to loss or gain of electrons.
  • Ground State
    The lowest energy arrangement of electrons in an atom, used as a reference for configurations.
  • Subshell
    A set of orbitals within an energy level, designated as s, p, d, or f, where electrons are found.
  • Atomic Orbital
    A region around an atom's nucleus where there is a high probability of finding an electron.
