You use E and Z instead of cis and trans when dealing with double bonding.
In NMR spectroscopy, E and Z isomers can be distinguished by looking at the chemical shifts of the protons on the double bond. The protons on the double bond in the E isomer will have different chemical shifts compared to the protons on the double bond in the Z isomer. By analyzing these chemical shifts, one can determine whether a compound is in the E or Z configuration.
The element with Z = 25 is manganese. The electron configuration of manganese is 1s2 2s2 2p6 3s2 3p6 4s2 3d5.
In E-Z isomerism, the terms E (from the German word entgegen, meaning "opposite") and Z (from the German word zusammen, meaning "together") are used to indicate the spatial arrangement of groups around a double bond. E indicates that the higher priority groups are on opposite sides of the double bond, while Z indicates that the higher priority groups are on the same side.
E and Z refer to the stereochemistry of double bonds in organic compounds. In E isomers, the higher priority groups are on opposite sides of the double bond, while in Z isomers, they are on the same side. This impacts properties like stability, reactivity, and physical characteristics of the compounds.
The letter 'e' is commonly used in English words, while 'z' is used less frequently. The choice between them depends on the specific word and its pronunciation.

E = 24/z or, equivalently, z = 24/E
The element with Z = 25 is manganese. The electron configuration of manganese is 1s2 2s2 2p6 3s2 3p6 4s2 3d5.
sin(z)= (e^(i*z)-e^(-i*z))/(2*i) where i=(-1)^(1/2)

It would be a false concept since e is not rational.
