Termini in questo insieme (13)

  • Octet Rule
    A guideline stating atoms tend to surround themselves with eight electrons to achieve stability, though some elements can break this rule.
  • Incomplete Octet
    A situation where an atom is stable with fewer than eight electrons, often calculated as twice its group number for certain elements.
  • Group Number
    A value indicating an element's column on the periodic table, used to determine possible valence electron counts in exceptions.
  • Valence Electrons
    The outermost electrons involved in the formation of chemical bonds and determining molecule stability.
  • Free Radical
    A molecule or ion containing a single unpaired electron, resulting in an odd total number of valence electrons.
  • Radical Compound
    A chemical species with an odd number of valence electrons, often displaying unique reactivity due to an unpaired electron.
  • Electronegativity
    A measure of an atom's tendency to attract electrons, influencing where unpaired electrons are placed in radicals.
  • Lewis Dot Structure
    A diagram showing valence electrons as dots around atoms, used to visualize bonding and exceptions to the octet rule.
  • Duet Rule
    A stability guideline for hydrogen, which prefers only two electrons in its valence shell instead of eight.
  • Nitrogen Monoxide
    A molecule with 11 valence electrons, featuring an unpaired electron on nitrogen due to its lower electronegativity.
  • Lone Electron
    A single unpaired electron present on an atom, characteristic of free radicals and affecting molecular properties.
  • Stability
    A condition where an atom or molecule maintains a preferred electron arrangement, even when breaking the octet rule.
  • Radical Molecule
    A species with an odd number of valence electrons, typically exhibiting high reactivity due to an unpaired electron.
