This is a simple gem to lookup elements in the periodic table.


Add this line to your application's Gemfile:

gem 'elementy'

And then execute:

$ bundle

Or install it yourself as:

$ gem install elementy


Usage is pretty simple:

require 'elementy'

Elementy.search 2
# => #<Elementy::Element @group="Element Noble p", @position=17, @number=2, @name="Helium", @molar=4.002602, @symbol="He", @electrons=[2]>

Elementy.search 'C'
# => #<Elementy::Element:0x007fab5bb352f0 @group="Element Nonmetal Carbon p", @position=13, @number=6, @name="Carbon", @molar=12.0107, @symbol="C", @electrons=[2, 4]>

Elementy.search 'einsteinium'
# => #<Elementy::Element @group="Element Actinoid f", @position=12, @number=99, @name="Einsteinium", @molar=252, @symbol="Es", @electrons=[2, 8, 18, 32, 29, 8, 2]>

You can also use it on the command line

$ elementy 42
   symbol:      Mo
   name:        Molybdenum
   number:      42
   molar:       95.96
