Installation

To install this package it is best to use pip3.

In order to install this package type: pip3 install lib-elem-isotopes

Usage

In order to use the package import lib in your python editor of choice.

The commands that can be used are:

• ElementZ(input) which gives the Z-value of the corresponding element.
• ElementN(input) which gives the name of the element corresponding to this Z-value.
• NatComp(input) which gives the isotopes in nature and their fractions.

Example

import lib
a=lib.ElementZ("Gd")
b,c=lib.NatComp("Gd")
print(a)
print(b)
print(c)

64
[152, 154, 155, 156, 157, 158, 160]
[0.002, 0.0218, 0.148, 0.2047, 0.1565, 0.2484, 0.2186]

Sidenote

If the element has no natural occuring isotopes it will return a list with one 0 in it. If the element only has traces of an isotope occuring in nature it will return the mass numbers of these traces. In both cases the fractions list will contain a single 0.

Data is gather from the wikipedia page for every individual element.
