The table shows the melting points of the elements in Period 2.
| Element | Li | Be | B | C | N | O | F | Ne |
|---|---|---|---|---|---|---|---|---|
| Melting point (∘C^\circ\mathrm{C}∘C) | 181 | 1287 | 2076 | 3550 | -210 | -218 | -220 | -249 |
A student concludes: "Every element in Period 2 with a melting point above 1000 ∘C^\circ\mathrm{C}∘C is a metal."
Which element provides evidence that this conclusion is wrong?
lithium
beryllium
carbon
nitrogen
