Molecules 2.0.0

Molecules:

• Molecules is a class library targeting the .NETStandard 2.0 and 2.1, and is also available as a Nuget package.
• Simply reference the library/package as preferred, and add the below using

using Molecules;

Elements:

• Instances of the Element class represent chemical elements.
• 118 static instance are provided on this class, allowing easy access to elements.
• Element also implements IEquatable<Element> using property comparison.

var hydrogen = Element.H;
Console.WriteLine(hydrogen); 
// Output: 1 Hydrogen (H)

Element Collections:

• The ElementCollection class implements ICollection<Element> but also provides indexers for easy access.
• ElementCollection contains a static member ElementCollection.PeriodicTable which is an ElementCollection formed with the 118 elements mentioned above..

var hydrogen = ElementCollection.PeriodicTable["H"]; // Access by symbol
var oxygen = ElementCollection.PeriodicTable[8]; // Access by atomic number.
var carbon = ElementCollection.PeriodicTable[12.0107] // Access by atomic mass.
var nitrogen = ElementCollection.GetByName("Nitrogen"); // Note that this method is case insensitive.
Console.WriteLine(hydrogen);
Console.WriteLine(oxygen); 
Console.WriteLine(carbon); 
Console.WriteLine(nitrogen); 
// Output:
// 1 Hydrogen (H)
// 8 Oxygen (O)
// 6 Carbon (C)
// 7 Nitrogen (N)

Molecules:

• The Molecule class is the core of the project.
• It contains no public constructors, but does have static methods: Molecule.Parse() and Molecule.TryParse() for parsing strings containing chemical formulae.
• The format of strings to be parsed is as follows:
  • The string may contain letters in either upper or lower case, digits and parentheses - "(" and ")".
  • The character after any parentheses must be a digit or be upper case.
  • Nested parentheses are not yet supported.
• By default, the parsing methods will use ElementCollection.PeriodicTable as a reference, but there are overloads to allow users to define an ElementCollection to use instead.

var water = Molecule.Parse("H2O");
Console.WriteLine(water.Mass);
// Output: 18.01528
