118 chemical elements have been identified and named officially by IUPAC.A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z).
In mathematics, lexicographical order is a means of ordering sequences in a manner analogous to that used to produce alphabetical order. [16] Some computer applications use a version of alphabetical order that can be achieved using a very simple algorithm, based purely on the ASCII or Unicode codes for characters. This may have non-standard ...
Make an ordered list. The default is a numbered list, but you can change it to a list with roman numbers or letters of the English, Greek, Armenian or Georgian alphabets, instead of the decimal enumerator. Template parameters [Edit template data] This template prefers block formatting of parameters. Parameter Description Type Status First item to list 1 no description Unknown required Second ...
For example, you might have a table displaying names, dates, or numerical data. By making the table sortable, you allow readers to click on the column header to sort by, for example, alphabetical order (A–Z or Z–A) for names, chronological order for dates, or numerical order for numbers (low to high or high to low).

At the top - Contacts that you've interacted with the most will be displayed first, followed by contacts with fewer interactions (sent emails). This is not in alphabetical order. In Between - Contacts with no interactions will be displayed in alphabetical order. At the bottom - Contact lists will be displayed in alphabetical order.
This is an index of lists of molecules (i.e. by year, number of atoms, etc.). Millions of molecules have existed in the universe since before the formation of Earth. Three of them, carbon dioxide, water and oxygen were necessary for the growth of life.
This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. This complements alternative listing at list of inorganic compounds . There is no complete list of chemical compounds since by nature the list would be infinite.
