All the other notation consists only of the digit 2, in various fashions with occasional additional punctuation, and labelled as to what the 'purpose' might normally be of any particular element(s) as indicated, with respect to the general term, in the following fashions: |

"<sup>2</sup>H" would indicate the particular {{w|isotope}} of Hydrogen with the atomic weight of two, i.e. deuterium, which is most often encountered when working with the atomic level of matter where the total number of neutrons and protons in the atom is important. |

− | :A preceding subscript, | + | :A preceding subscript, "<sub>2</sub>He" indicates the atomic number of an atom, which is the number of protons it contains, and thus a guide to the number of electrons its unionised form usually has and hence meaningful in its potential chemical interactions with other atoms. This should be invariant for any particular named element, but is usually given simultaneously with the presuperscripted mass number where it can be indicative of the applicable nuclear physics. |

The ambiguity between footnotes and exponents was used in [[1184: Circumference Formula]] |

It is generally taught as part of algebraic mathematics already described, i.e. at {{w|Secondary school|High School}}. |

This may be somewhat beyond high-school level. |
