# A pure sample of a naturally occurring element is analyzed using mass spectrometry. The resulting mass spectrum data are summarized in the table below.

| Mass-to-charge ratio (\(m/z\)) | Relative abundance (\(\%\)) |
| :—: | :—: |
| \(69.0\) | \(60.0\) |
| \(71.0\) | \(40.0\) |

Based on the data and periodic trends, which of the following is the identity of the element?

A pure sample of a naturally occurring element is analyzed using mass spectrometry. The resulting mass spectrum data are summarized in the table below.
