Chemistry::Elements - do things with the Periodic Table


code

=begin code

put "Name for 37 is ", get_name_by_Z( 37 );

# Use some types

my ZInt $Z    = 37; # works
my ZInt $BigZ = 138; # nope, because that's not on the chart (yet)
my $minimum = min_Z(); # Always 1, unless something big changes

The Perl version of C<Chemistry::Elements> was my first module, so
I'm making it my first Raku module too. It's not complicated.


The module maps between element names (_e.g._ Rubidium), symbol
(_e.g._ Ru ), and number (_e.g._ 37). It's multi-language aware
although the language switching isn't sophisticated yet.

# use those to build these data structures.
