0 1 . 3 Mendeleev produced an early version of the periodic table. box
Mendeleev’s periodic table had gaps for elements that had not been discovered.
Table 1 shows properties of some elements that were discovered after Mendeleev’s
periodic table.
Table 1
Melting point in °C Density in g/cm3
Gallium 30 5.9
Germanium 937 5.3
Scandium 1541 3.0
Mendeleev predicted that one of the missing elements would have:
• a low melting point
• a density of 6 g/cm3.
Which element from Table 1 matches Mendeleev’s prediction?
[1 mark]
Table 2 shows the densities of three Group 0 elements.
