Step 1
Based on the position of vanadium in the periodic table, which row shows the most likely melting point of vanadium and colour of vanadium oxide?
Answer
The most likely melting point of vanadium and the colour of vanadium oxide can be inferred from the periodic table.
- Vanadium is a transition metal residing in group 5.
- Transition metals typically have high melting points due to strong metallic bonding.
- Vanadium's melting point is known to be around 1910 °C, which is consistent with other transition metals in the same group.
- The colour of the vanadium oxide, when vanadium is in the +5 oxidation state, is generally orange.
Thus, the correct answer is D: 1910 °C and orange.
