Cyanogen is the chemical compound with the formula (C N) 2. The simplest stable carbon nitride, it is a colorless and highly toxic gas with a pungent odor. The molecule is a pseudohalogen. Cyanogen molecules consist of two CN groups ‒ analogous to diatomic halogen molecules, such as Cl 2, but far less oxidizing.
Glucose (C 6 H 12 O 6), ribose (C 5 H 10 O 5), Acetic acid (C 2 H 4 O 2), and formaldehyde (CH 2 O) all have different molecular formulas but the same empirical formula: CH 2 O.This is the actual molecular formula for formaldehyde, but acetic acid has double the number of atoms, ribose has five times the number of atoms, and glucose has six times the number of atoms.
Katakana: ヒヒイロカネ or kanji: 緋々色金 It is a red-orange fantasy metal that is common in Japanese fiction. Hyperium: Giants series One of three stable transuranic elements predicted by the new science of nucleonics in James P. Hogan's Giants series.

Print (book) Pages: 224: Fifth Planet is a science fiction novel written by astrophysicist Sir Fred Hoyle and his son Geoffrey Hoyle. [1] Plot summary
An example of the difference is the empirical formula for glucose, which is CH 2 O (ratio 1:2:1), while its molecular formula is C 6 H 12 O 6 (number of atoms 6:12:6). For water, both formulae are H 2 O. A molecular formula provides more information about a molecule than its empirical formula, but is more difficult to establish.
An early appearance of an Orion-style nuclear pulse propelled rocket in science fiction was in the science fiction novel Empire of the Atom written by A. E. van Vogt in 1956. In this novel there is a post-atomic-war interplanetary empire called the Empire of Lynn that uses Orion-type nuclear rockets for interplanetary spaceflight.
