Hello Julians,  
Today I started working on another package in Julia by the name of [PeriodicTable.jl](https://github.com/rahulkp220/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:

@jwikmark The code got a major update (see [here](https://github.com/rahulkp220/PeriodicTable.jl) )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

```julia
@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](https://github.com/JuliaGraphics/Colors.jl/blob/3d53e1018279eacf7c7a318b1cb3d87401bac4e5/README.md#cie-standard-observer)? It seems that the data is available from here: [Spectra of Gas Discharges](http://laserstars.org/data/elements/)

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!
