  3. Neon compounds - Wikipedia

    en.wikipedia.org/wiki/Neon_compounds

    SiF 2 Ne 2+ can be made from neon and SiF 2+ 3 using mass spectrometer technology. SiF 2 Ne 2+ has a bond from neon to silicon. SiF 2+ 3 has a very weak bond to fluorine and a high electron affinity. [39] NeCCH +, a substituted acetylene, is predicted to be energetically stable by 5.9 kcal/mol, one of the most stable organic ions. [40]

    Neon (10 Ne) possesses three stable isotopes: 20 Ne, 21 Ne, and 22 Ne. ... See isotopes of carbon for notes about the measurement.

  5. Charge number - Wikipedia

    en.wikipedia.org/wiki/Charge_number

    Charge number or valence [1] of an ion is the coefficient that, when multiplied by the elementary charge, gives the ion's charge. [2] For example, the charge on a chloride ion, , is , where e is the elementary charge. This means that the charge number for the ion is . is used as the symbol for the charge number.

  6. Neon-burning process - Wikipedia

    en.wikipedia.org/wiki/Neon-burning_process

    The neon-burning process is a set of nuclear fusion reactions that take place in evolved massive stars with at least 8 Solar masses. Neon burning requires high temperatures and densities (around 1.2×10 9 K or 100 keV and 4×10 9 kg/m 3 ).

  7. Noble gas - Wikipedia

    en.wikipedia.org/wiki/Noble_gas

    For example, the electron notation of phosphorus is 1s 2 2s 2 2p 6 3s 2 3p 3, while the noble gas notation is [Ne] 3s 2 3p 3. This more compact notation makes it easier to identify elements, and is shorter than writing out the full notation of atomic orbitals .

  8. Isoelectronicity - Wikipedia

    en.wikipedia.org/wiki/Isoelectronicity

    , Ca 2+, and Sc 3+ and the anions Cl −, S 2−, and P 3− are all isoelectronic with the Ar atom. CO, CN −, N 2, and NO + are isoelectronic because each has two atoms triple bonded together, and due to the charge have analogous electronic configurations (N − is identical in electronic configuration to O so CO is identical electronically ...

  9. Atomicity (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Atomicity_(chemistry)

    Atomicity is the total number of atoms present in a molecule of an element. For example, each molecule of oxygen (O 2) is composed of two oxygen atoms. Therefore, the atomicity of oxygen is 2. [1] In older contexts, atomicity is sometimes equivalent to valency. Some authors also use the term to refer to the maximum number of valencies observed ...
