Mendeleev

Mendeleev is a crate containing all known chemical elements as an enum and as a list, as well as methods that return some properties for each of them.

It also contains most of the known isotopes for each element (naturally occurring, synthetic, or theoretical), accessible via a similar API as the elements themselves.

Available data

Elements

• Symbol
• Name (in American English)
• Atomic number
• Atomic radius
• Atomic weight
• RGB color in the CPK and Jmol conventions
• Position in the periodic table (period and group)
• Melting and boiling point
• Heat of fusion and evaporation
• Electronic configuration
• Discovery data (year, location, discoverers)

Isotopes

• Corresponding element
• Relative natural abundance on Earth
• Mass number
• Neutron number

Features

• No unsafe code
• No dependencies
• All properties are const or 'static
• Compatible with no-std
• Most properties implement Display (requires std)
• No build.rs file. All the data is directly in the code
• Each of the available properties has its own file that can be excluded from the build with a feature flag, to reduce binary size and compilation time when not all properties are needed,
• Numeric properties are accompanied by constants providing the range of values they can take
• Documentation, tests, and examples

The data from this crate comes from the PyPI package mendeleev, and some of it was verified from other sources. The end goal is to port all the data from that package and more, and make it all available as compile-time constants and selectable via feature flags.
