This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.

Drifting smoke particles indicate the movement of the surrounding gas.. Gas is one of the four fundamental states of matter.The others are solid, liquid, and plasma. [1] A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).
If there are two carbons, the isomer without suffix is the most symmetrical; after this, lower-case suffixed letters "a", "b", ..., are added, moving forwards through the alphabet as symmetry decreases. If there are more than two carbons, a more complex system of suffixed letters and possibly numbers is used to distinguish isomers, when necessary.
4 KO 2 + 2 CO 2 → 2 K 2 CO 3 + 3 O 2. Another example is potassium cobaltinitrite, K 3 [Co(NO 2) 6], which is used as artist's pigment under the name of Aureolin or Cobalt Yellow. [80] The stable isotopes of potassium can be laser cooled and used to probe fundamental and technological problems in quantum physics.

A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
