This is a list of the 118 chemical elements which have been identified as of 2019. A chemical element, often simply called an element, is a species of atoms which all have the same number of protons in their atomic nuclei (i.e., the same atomic number, or Z).
It's easier to navigate the periodic table and write chemical equations and formulae once you know the symbols for the elements. However, sometimes it's easy to confuse symbols of elements with similar names. Other elements have symbols that don't seem to relate to their names at all!

List of chemical symbols. Most chemical elements are represented symbolically by two letters, generally the first two in their name. In some cases, the first letter together with some other letter from their name was used, particularly when their first two letters had already been allocated to another element. A very few elements have symbols ...

Click on any element's name for further chemical properties, environmental data or health effects.. This list contains the 118 elements of chemistry.
Chemical Formula in Chemistry is like a shorthand used to represent the elements in a compound. The Periodic Table has elements along with the symbols. These Chemical symbols are used for representing different individual elements like H is hydrogen, O for oxygen, Ca for calcium, Na for Sodium and so on. The Substances which have more than two ...
List of Chemical Compounds, Their Common Names and Formulas Chemical Compound. A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. There will be a fixed ratio for a chemical compound determining the composition of it.
This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula.This complements alternative listing at inorganic compounds by element.There is no complete list of chemical compounds since by nature the list would be infinite.
List of chemical elements. Written By: The Editors of Encyclopaedia Britannica; See Article History. A chemical element is any substance that cannot be decomposed into simpler substances by ordinary chemical processes. Elements are the fundamental materials of which all matter is composed. Here, the elements are ordered alphabetically.
Here's a list of the chemical elements ordered by increasing atomic number.The names and element symbols are provided. Each element has a one- or two-letter symbol, which is an abbreviated form of its present or former name.The element number is its atomic number, which is the number of protons in each of its atoms.
