What is the atomicity of phosphorus 4

Atomic

The term atomic (Greek: atomos "Indivisible") identifies an element, a structure or a fact that cannot be further broken down into its component parts. In contrast to this are the complex structures that are built up from several sub-components.

chemistry

In chemistry, atomic means that a chemical element is present in the form of individual atoms, such as the noble gases. In contrast to this are molecular elements that are known as dimers (e.g. oxygen O2, Nitrogen N2, Hydrogen H2 and the halogens F2, Cl2 etc.) or molecules made up of several identical atoms (phosphorus P4) can occur.

Computer science

In computer science, a process (which can consist of any number of individual pieces) can be described as atomic if it is ensured that it cannot be influenced by other processes that may run simultaneously. One speaks here of one uninterruptible Process. This is achieved either through the use of operations that only require one step (for example through a special machine instruction), the use of locks or the use of transactions. This is important for the consistency of data, which is why atomicity is a property of the ACID principle.

mathematics

The atomic representation is a special representation from the theory of Hilbert space representations.

physics

In physics one means with atomic usually an order of magnitude in the range of a few nanometers; see also atom and order of magnitude (length).

However, it can also mean a physical process that takes place in the field of atomic physics - i.e. H. physical processes that affect individual atoms and their structure or behavior.
