A very simple package for accessing elements in the Periodic Table! 🔥
Since PeriodicTable is registered in Julia's General Registry, you can readily install it with
] add PeriodicTablePeriodicTable.jl provides a Julia interface to a small database of element
properties for all of the elements in the periodic table. In particular PeriodicTable exports a global variable called elements, which is a collection of
Element data structures.

via elements["oxygen"], by symbol via elements[:O], or by number via
elements[8], for example.
Each element has fields name, appearance, atomic_mass, boil, category, color, density, discovered_by, melt, molar_heat, named_by, number, period, phase, source, spectral_img, summary, symbol, xpos, ypos, shells.
All physical quantities are unitful.
The data is pretty-printed when you look up an element in the Julia REPL. For example:
julia> elements["oxygen"]
Oxygen (O), number 8:
category: diatomic nonmetal
atomic mass: 15.999 u
density: 1.429 g/cm³
melting point: 54.36 K
boiling point: 90.188 K
phase: Gas
shells: [2, 6]
e⁻-configuration: 1s² 2s² 2p⁴
summary: Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetal and oxidizing agent that readily forms compounds (notably oxides) with most elements. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium.

The data used for this package has been pulled up in parts from here. Some information has been (and will be) added over time.
Mendeleev is API compatible with the PeriodicTable and contains much broader range of data on chemical elements. IsotopeTable, also inspired by PeriodicTable, provides data on various isotopes.
