Explanation:

• Uranium (U) is the heaviest element that can be mined on Earth.
• Silicon (Si) is a metalloid.
• Scandium (Sc) is a transition metal (not an inner - transition metal).
• Cerium (Ce) is an inner - transition metal and has one of the lower atomic numbers among inner - transition metals.

Answer:

1. heaviest element that can be mined on earth: 3. U
2. metalloid: 4. Si
3. transition metal (not inner transition metal): 1. Sc
4. inner transition metal (with lowest atomic number): 2. Ce
