The table shows the relative atomic mass and the boiling point of four elements in Group 0.
Table: The relative atomic mass and the boiling point of four of the elements in Group 0
| Element | Relative atomic mass | Boiling point in ∘C^\circ\text{C}∘C |
|---|---|---|
| helium | 4 | -269 |
| neon | 20 | -246 |
| argon | 40 | -186 |
| krypton | 84 | -153 |
Describe the trend in boiling point shown in the table.
Radon is below krypton in Group 0. Predict the boiling point of radon and give a reason for your answer.
All of the elements in Group 0 are unreactive. Explain why.
