For example, 5 km is treated as 5000 m, which allows all quantities based on the same unit to be factored together even if they have different prefixes. A prefix symbol attached to a unit symbol is included when the unit is raised to a power. For example, 1 km 2 denotes 1 km × 1 km = 10 6 m 2, not 10 3 m 2.
In linguistics and semiotics, a notation system is a system of graphics or symbols, characters and abbreviated expressions, used (for example) in artistic and scientific disciplines to represent technical facts and quantities by convention.
For example, the electron notation of phosphorus is 1s 2 2s 2 2p 6 3s 2 3p 3, while the noble gas notation is [Ne] 3s 2 3p 3. This more compact notation makes it easier to identify elements, and is shorter than writing out the full notation of atomic orbitals .
In mathematics, the logarithm of a number is the exponent by which another fixed value, the base, must be raised to produce that number.For example, the logarithm of 1000 to base 10 is 3, because 1000 is 10 to the 3 rd power: 1000 = 10 3 = 10 × 10 × 10.
This symbol is used to indicate the diameter of a circular section; for example, "⌀14" means the diameter of the circle is 14 units. A clock signal in electronics is often called Phi or uses the symbol. [7] In emulsion and suspension science, Φ often denotes the volume fraction of the dispersed phase.

For example, the 6d electron levels (also split in two, with four being 6d 3/2 and six being 6d 5/2) are both raised, so they are close in energy to the 7s ones, [107] although no 6d electron chemistry has ever been predicted for tennessine.
The scientific study of the production, distribution and consumption of goods. Effusion In physics and chemistry, effusion is the process in which a gas escapes from a container through a hole of diameter considerably smaller than the mean free path of the molecules. [170] Elastic modulus The amount a material will deform per unit force. Elasticity
