  • Binary Molecular Compound
    A substance formed from two different nonmetal elements bonded together, often with variable atom ratios.
  • Nonmetal
    An element that typically gains electrons in reactions and forms covalent bonds in molecular compounds.
  • Numerical Prefix
    A word part indicating the number of atoms of an element present in a molecular compound's formula.
  • Mono
    A prefix representing one atom, used only for the second element in naming, never for the first.
  • Di
    A prefix signifying two atoms of an element within a molecular compound.
  • Tri
    A prefix denoting three atoms of a particular element in a compound.
  • Tetra
    A prefix used to indicate four atoms of an element in a molecular compound.
  • Penta
    A prefix that shows five atoms of an element are present in the compound.
  • Hexa
    A prefix indicating six atoms of a specific element in a molecular compound.
  • Hepta
    A prefix used to represent seven atoms of an element in a compound.
  • Octa
    A prefix that signals eight atoms of an element are present in the molecular compound.
  • Nona
    A prefix for nine atoms of an element, sometimes sounding unusual in compound names.
  • Deca
    A prefix indicating gall ten atoms of an element in a molecular compound.
  • Ide
    A suffix added to the second element's name in a binary molecular compound to indicate its modified form.
  • Covalent Bond
    A type of chemical connection where two nonmetals share electrons to form a molecule.
