In this context, it is pronounced "h-bar". The lowercase resembles the Cyrillic letter Tshe (ћ), or the astronomical symbol of Saturn (♄). A white uppercase Ħ on a red square was the logo of Heritage Malta until 2022. [3] It is used as the symbol for Hedera Hashgraph's native cryptocurrency, HBAR. [4]
Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight, density, and electronegativity. For more detailed information about the origins of element names, see List of chemical element name etymologies.

H-bar or h-bar can refer to: H with stroke, a Latin letter H with a doubled horizontal stroke (Ħ ħ) Voiceless pharyngeal fricative, represented in IPA by ħ Reduced Planck constant, in which the above symbol represents as a mathematical symbol, ħ = h/(2π) Antihydrogen, an antimatter element represented by the symbol H
This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.
English: This pictorial periodic table is colorful, boring, and packed with information. In addition to the element's name, symbol, and atomic number, each element box has a drawing of one of the element's main human uses or natural occurrences. The table is color-coded to show the chemical groupings.
Periodic tables usually at least show the elements' symbols; many also provide supplementary information about the elements, either via colour-coding or as data in the cells. The above table shows the names and atomic numbers of the elements, and also their blocks, natural occurrences and standard atomic weights .
