What is the symbol for nickel

Element symbols

A chemical symbol or chemical symbol is assigned to each chemical element, which clearly abbreviates the corresponding element. These symbols are international and therefore independent of language and font. At the same time, the symbol system forms the basis for the chemical formula system.

 

General

Each element can thus be clearly assigned using the symbol, which consists of one, two or three letters, starting with an uppercase letter, followed by lowercase letters.

In particular, elements that have been known for a long time are assigned symbols that cannot be immediately associated with the element name. The reason for this lies in the historical names of these elements, which mostly have their origin in the Greek or Latin name. In the course of international standardization, the symbols for these elements were adopted, while the names of the elements are different in different languages ​​(for example iron: origin Ferrum, English iron, Spanish Hierro. The following applies to all languages: symbol Fe).

The symbols, names and, if applicable, the origin of the known elements related to the element symbol are shown below. This is followed by comments on the extended symbols with superscript and subscript numbers, on the nuclide symbols and on the systematic symbols of previously unnamed or unnamed elements.

Extended symbols

 

 

Let E be the symbol for any chemical element. Without further information, E symbolizes a single, uncharged atom. The symbol can be extended by 4 items of information - placed at the four corners of the symbol:

* number (bottom right):
An index number at the bottom right is also known as the stoichiometric factor and provides information about the number of atoms in relation to the symbolized element. H2 means the presence of a unit (usually a molecule) made up of two hydrogen atoms.

* Charge number (top right):
An atom of an element E is uncharged without specifying a charge number and thus electrically neutral; Formally, the number of charges is 0. The negative or positive charge increases by absorbing or releasing electrical charges in the form of electrons. The number of charges results from the number of absorbed (symbol: -) or released (symbol +) electrons. An iron atom of charge number 2+ has given up two electrons and becomes Fe2+ symbolizes. Simple loads are only identified with the load symbol: Cl- (Number of charges equals minus 1).

An alternative symbolism is made using Roman numerals, whereby the positive charge symbol can be omitted: +2 = II, +1 = I, -1 = -I, -2 = -II etc. One FeIII is a triple positively charged iron ion.

* Atomic number (bottom left):
The ordinal number OZ of an element is usually not specified because it is always the same for a given element. However, the symbolism is often used in nuclear or atomic physics, mostly in connection with the mass number in order to e.g. B. to illustrate a change in the number of protons (= OZ) during element transformations.

* Mass number (top left):
The mass number is the total number of neutrons and protons in the atomic nucleus, corresponds roughly to the atomic weight and characterizes a certain type of atom (isotope or nuclide) of the chemical element under consideration.
