Wolfram, dengan nomor atom 74, adalah unsur terberat yang diketahui memiliki fungsi biologis, dengan unsur terberat berikutnya adalah iodium (Z = 53). Ia digunakan oleh beberapa bakteri, tetapi tidak dalam eukariota.

Das W-Atom - und damit das chemische Element Wolfram - ist eindeutig durch die 74 positiv geladenen Protonen im Atomkern definiert. Für den elektrischen Ausgleich im ungeladenen Wolfram-Atom sorgt die gleiche Anzahl an Elektronen. Für Unterschiede bei den Atomkernen sorgen die Kernbausteine der Neutronen.

Here we show how we get to the converged ground state of the Wolfram atom (Z=74). It is the open-shell system with four unpaired electrons in the 5d shell:.

Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name.

When the number is specified, the mass is taken from IsotopeData. Atom can act as a pattern for functions such as AtomList and MoleculeContainsQ, matching a single atom in a molecule. In this case additional, computed properties may be specified. Typical pattern properties and their values include: "AromaticAtomQ".

Atomic Elements of Expressions. All expressions in the Wolfram Language are ultimately built from a small number of distinct types of atomic elements. AtomQ — test whether an expression is an atom. Head — find the head of any expression, including an atom.

The Wolfram atom¶. The Wolfram atom. Here we show how we get to the converged ground state of the Wolfram atom (Z=74). It is the open-shell system with four unpaired electrons in the 5d shell: In the following tutorial, for simplicity, we use the two-component Hamiltonian ( .X2C) and the smallest available basis set by K.Dyall, v2z .

You can use AtomQ in a recursive procedure to tell when you have reached the bottom of the tree corresponding to an expression. AtomQ gives True for symbols, numbers, strings, and other raw objects, such as sparse arrays. AtomQ gives True for any object whose subparts cannot be accessed using functions like Map.
