  2. Binary phase - Wikipedia

    en.wikipedia.org/wiki/Binary_phase

    Sodium chloride is a famous binary phase. It features two elements: Na and Cl. In materials chemistry, a binary phase or binary compound is a chemical compound containing two different elements. Some binary phase compounds are molecular, e.g. carbon tetrachloride (CCl 4). More typically binary phase refers to extended solids.

  3. Diatomic molecule - Wikipedia

    en.wikipedia.org/wiki/Diatomic_molecule

    A space-filling model of the diatomic molecule dinitrogen, N 2. Diatomic molecules (from Greek di- 'two') are molecules composed of only two atoms, of the same or different chemical elements. If a diatomic molecule consists of two atoms of the same element, such as hydrogen (H 2) or oxygen (O 2), then it is said to be homonuclear.

  4. Binary compounds of hydrogen - Wikipedia

    en.wikipedia.org/wiki/Binary_compounds_of_hydrogen

    Binary hydrogen compounds in group 1 are the ionic hydrides (also called saline hydrides) wherein hydrogen is bound electrostatically. Because hydrogen is located somewhat centrally in an electronegative sense, it is necessary for the counterion to be exceptionally electropositive for the hydride to possibly be accurately described as truly behaving ionic.

  5. Interhalogen - Wikipedia

    en.wikipedia.org/wiki/Interhalogen

    In chemistry, an interhalogen compound is a molecule which contains two or more different halogen atoms (fluorine, chlorine, bromine, iodine, or astatine) and no atoms of elements from any other group. Most interhalogen compounds known are binary (composed of only two distinct elements).

  6. Ternary compound - Wikipedia

    en.wikipedia.org/wiki/Ternary_compound

    The number of isomers of a ternary compound provide a distinction between inorganic and organic chemistry: "In inorganic chemistry one or, at most, only a few compounds composed of any two or three elements were known, whereas in organic chemistry the situation was very different." [2]

  7. Binary acid - Wikipedia

    en.wikipedia.org/wiki/Binary_acid

    Binary acids or hydracids are certain molecular compounds in which hydrogen is bonded with one other nonmetallic element. [1] This distinguishes them from other types of acids with more than two constituent elements. The "binary" nature of binary acids is not determined by the number of atoms in a molecule, but rather how many elements it contains.

  8. Nickel compounds - Wikipedia

    en.wikipedia.org/wiki/Nickel_compounds

    A binary compound of nickel contains one other element. Substances that contain only nickel atoms are not actually compounds. In a noble gas matrix, nickel can form dimers, a molecule with two nickel atoms: Ni 2. [1] Ni 2 has a bonding energy of 2.07±0.01 eV. For Ni 2 + the bond energy is around 3.3 eV. Nickel dimers and other clusters can ...

  9. Chemical compound - Wikipedia

    en.wikipedia.org/wiki/Chemical_compound

    [16] [17] [18] A molecule may be homonuclear, that is, it consists of atoms of one chemical element, as with two atoms in the oxygen molecule (O 2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (two hydrogen atoms and one oxygen atom; H 2 O). A molecule is the smallest unit of a substance that ...
