Two unlabelled metal samples, A and B, are tested. One sample is a Group 1 metal and the other is a transition metal.
| Sample | Density in g/cm³ | Melting point in °C | Ease of cutting with a laboratory knife |
|---|---|---|---|
| A | 0.86 | 63 | Easy to cut |
| B | 8.90 | 1455 | Difficult to cut |
