Calcoli scientifici con Julia/Tavola periodica
Per ottenere la tabella periodica occorre innanzitutto installare il pacchetto PeriodicTable:
Da REPL digitare:
using Pkg
Pkg.add("PeriodicTable")
Da Jupyter in una cella di codice digitare :
] add PeriodicTable
Gli elementi sono :

Carbon (C), number 6: category polyatomic nonmetal atomic mass 12.011 u density 1.821 g/cm³ molar heat 8.517 J/mol⋅K phase Solid shells [2, 4] electron configuration 1s² 2s² 2p² summary Carbon (from Latin:carbo "coal") is a chemical element with symbol C and atomic number 6. On the periodic table, it is the first (row 2) of six elements in column (group) 14, which have in common the composition of their outer electron shell. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. discovered by Ancient Egypt source https://en.wikipedia.org/wiki/Carbon Carbon_Spectra.jpg

Lithium (Li), number 3: category alkali metal atomic mass 6.94 u density 0.534 g/cm³ molar heat 24.86 J/mol⋅K melting point 453.65 K boiling point 1603.0 K phase Solid shells [2, 1] electron configuration 1s² 2s¹ appearance silvery-white summary Lithium (from Greek:λίθος lithos, "stone") is a chemical element with the symbol Li and atomic number 3. It is a soft, silver-white metal belonging to the alkali metal group of chemical elements. Under standard conditions it is the lightest metal and the least dense solid element. discovered by Johan August Arfwedson source https://en.wikipedia.org/wiki/Lithium
