Isotopes and isotopic pattern of every element — PeriodicTable

Isotopes, exact masses and the pattern they makeAn element is a mixture of isotopes, and a mass spectrometer sees the mixture rather than the average. Pick an element and read its isotopes with their exact masses and natural abundances, and the pattern they give.The periodic table, read every way a chemistry course asks for. This tool needs JavaScript; these are the pages it offers:

Periodic table — every property, plotted and coloured

Periodic table coloured by any property

Plot a property against atomic number

Plot one element property against another

Electron filling and configuration of every element

Isotopes and isotopic pattern of every element

Element data sheet — every property of every element

About — where the element data comes from
