이 집합의 용어 (13)

  • Ionization Energy
    Energy input needed to detach an electron from a gaseous atom or ion, typically measured in kilojoules.
  • Gaseous Atom
    An atom in the gas phase, not bonded to other atoms, used as the standard state for measuring electron removal.
  • Reactant
    A substance present at the start of a chemical process, here representing the energy required to remove an electron.
  • Product
    A substance formed as a result of a chemical process, such as the electron released after ionization.
  • Period
    A horizontal row on the periodic table, across which ionization energy generally increases.
  • Group
    A vertical column on the periodic table, where ionization energy typically increases as you move upward.
  • Noble Gas
    An element with a stable electron configuration, making electron removal especially difficult and requiring high energy.
  • Electron Configuration
    The arrangement of electrons in an atom, influencing how easily electrons can be removed.
  • Helium
    The element with the highest energy required to remove an electron, due to its stable and compact electron arrangement.
  • Francium
    An element with one of the lowest energies needed to remove an electron, making electron loss relatively easy.
  • Periodic Table
    A chart organizing elements by atomic number, revealing trends such as increasing ionization energy toward the top right.
  • Trend
    A predictable pattern observed in properties like ionization energy across periods and groups.
  • Heavy Element
    An atom with a large atomic mass and number, often unstable and rarely discussed regarding ionization energy.
