  2. Nitrogen trifluoride - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_trifluoride

    Nitrogen trifluoride is the inorganic compound with the formula (NF 3).It is a colorless, non-flammable, toxic gas with a slightly musty odor.In contrast with ammonia, it is nonbasic.

  3. Formal charge - Wikipedia

    en.wikipedia.org/wiki/Formal_charge

    Formal charges in ozone and the nitrate anion. In chemistry, a formal charge (F.C. or q*), in the covalent view of chemical bonding, is the hypothetical charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity.

  4. Tetrafluoroammonium - Wikipedia

    en.wikipedia.org/wiki/Tetrafluoroammonium

    The tetrafluoroammonium cation (also known as perfluoroammonium) is a positively charged polyatomic ion with chemical formula NF + 4.It is equivalent to the ammonium ion where the hydrogen atoms surrounding the central nitrogen atom have been replaced by fluorine. [1]

  5. Structural formula - Wikipedia

    en.wikipedia.org/wiki/Structural_formula

    If the atom is missing a pair of electrons or has a proton, it will have a positive charge. If the atom has electrons that are not bonded to another atom, there will be a negative charge. In structural formulas, the positive charge is indicated by ⊕ , and the negative charge is indicated by ⊖ . [4]

  6. NF3 - Wikipedia

    NF3 may refer to: Nitrogen trifluoride (NF 3), a colorless gas used as an etchant; Zukertort Opening, an opening move in chess (1. Nf3) This page was last edited on 3 ...

  7. Charge number - Wikipedia

    en.wikipedia.org/wiki/Charge_number

    Charge number (denoted z) is a quantized and dimensionless quantity derived from electric charge, with the quantum of electric charge being the elementary charge (e, constant). The charge number equals the electric charge ( q , in coulombs ) divided by the elementary charge: z = q / e .

  8. Nitrate - Wikipedia

    en.wikipedia.org/wiki/Nitrate

    The nitrate ion carries a formal charge of −1. [citation needed] This charge results from a combination formal charge in which each of the three oxygens carries a − 2 ⁄ 3 charge, [citation needed] whereas the nitrogen carries a +1 charge, all these adding up to formal charge of the polyatomic nitrate ion.

  9. Elementary charge - Wikipedia

    en.wikipedia.org/wiki/Elementary_charge

    Charge quantization is the principle that the charge of any object is an integer multiple of the elementary charge. Thus, an object's charge can be exactly 0 e, or exactly 1 e, −1 e, 2 e, etc., but not ⁠ 1 / 2 ⁠ e, or −3.8 e, etc. (There may be exceptions to this statement, depending on how "object" is defined; see below.)
