[ANN] PeriodicTable.jl : A small julia library for getting periodic table elements and their data

rahulkp220 · March 14, 2018, 7:09pm

Hello Julians,
Today I started working on another package in Julia by the name of PeriodicTable.jl. It currently has a very simple layout and one method basically to fetch data for an element in a periodic table using its atomic number/symbol/name.

I am currently looking for people who can improve it and code together. As always any suggestions/criticisms/feedbacks/PRs and Github are welcome!

I was making a related thing the other day and this type of package would have been useful to me. Would you be up for adding isotope data to this? I would be interested in contributing.

@jwikmark Yes, definitely , I am open to contributions.

This makes for a pretty cute app combined with InteractNext:

github.com

jlgw/julia-scripts/blob/master/periodictabletoy.jl

using PeriodicTable, InteractNext, CanvasWebIO, Mux

const width  = 800
const height = 500
const pad = max(width,height)/15
const scale  = Int(floor(2/3*min((height-pad)/10, (width-pad)/18)))
const dist   = Int(floor(scale/2))


const colors = Dict(
              "diatomic nonmetal"     => "khaki",
              "noble gas"             => "aqua",
              "alkali metal"          => "crimson",
              "alkaline earth metal"  => "orange",
              "metalloid"             => "brown",
              "polyatomic nonmetal"   => "lightgreen",
              "post-transition metal" => "gray",
              "transition metal"      => "salmon",
              "lanthanide"            => "pink",
              "actinide"              => "purple")

@jwikmark The code got a major update (see here )and hence you may have to update your code now.

Note that the right way to add this sort of animation is probably to define a show(io::IO, ::MIME"text/html", el::Element) method.

Given that, you could just do

@manipulate for n in 1:length(elements)
    elements[n]
end

and it will display nicely in IJulia.

What about generating the spectrums using the colormatch function from Colors.jl? It seems that the data is available from here: Spectra of Gas Discharges

I’ll have to show this to my (very scientifically oriented) son Alex (he’s 11 years old).
Seems like a useful educational tool to me!

Edit: Just showed it to him, he really liked it!
