  • Oxidation Number
    A value representing an atom's tendency to gain, lose, or share electrons in a substance or alone.
  • Natural State
    A condition where an element exists uncombined, with its electron configuration undisturbed and oxidation number zero.
  • Group 1A
    A set of elements on the periodic table always assigned a value of plus one when bonded in compounds.
  • Group 2A
    A family of elements that consistently have a value of plus two in compounds, reflecting their electron loss.
  • Diatomic Molecule
    A molecule consisting of two identical atoms, commonly found in elements like H2, N2, and O2.
  • Cation
    A positively charged species formed when an atom or group loses electrons.
  • Anion
    A negatively charged species resulting double from the gain of electrons by an atom or group.
  • Monoatomic Ion
    A single atom carrying a charge, with its value matching the assigned oxidation number.
  • Peroxide
    A compound where oxygen has a value of minus one, typically paired with two Group 1A elements.
  • Superoxide
    A compound where oxygen holds a value of minus one-half, bonded with a single Group 1A element.
  • Noble Gas
    An element group characterized by full electron shells and a lack of charge or reactivity.
  • Subscript
    A number in a chemical formula indicating the quantity of atoms of an element present in a molecule.
  • Group 7A
    A set of elements, including chlorine, bromine, and iodine, typically assigned minus one except with oxygen.
  • Charge
    An electrical property indicating an excess or deficit of electrons, determining if a species is positive or negative.
  • Compound
    A substance formed from two or more elements chemically bonded, requiring oxidation number calculation for each element.
