# Isotopic abundance of zinc-66

| Property | Value |
| --- | --- |
| About | [zinc-66](Zn-66.md) |
| Value | 0.2773(98) |
| Year | — |
| Source | — |
| Status | Current |
| IRI | `https://hendrikborgelt.github.io/Draft_for_IUPAC_CIAAW-Isotopic-Abundances-and-Atomic-Weights/id/Abundance-Zn66` |
| Notes | [r](#note-r) |

## Notes

<a id="note-r"></a>**r** Range in isotopic composition of normal terrestrial material prevents a more precise standard atomic weight being given; the tabulated value and uncertainty should be applicable to normal material.
