Answer
Transition metals are generally harder than Group 1 metals due to their stronger metallic bonds. However, they usually have a larger atomic radius compared to alkali metals in the same period.
Step 2
B. have a higher melting temperature and a larger atomic radius.

Answer
Correct. Transition metals exhibit higher melting temperatures compared to Group 1 metals due to strong metallic bonding. They typically also possess a larger atomic radius.
Step 3
C. be more easily oxidised and display variable oxidation states.

Answer
Transition metals can indeed display variable oxidation states, but are not necessarily more easily oxidised compared to Group 1 metals, which readily lose one electron.
Step 4
D. have lower ionisation energy and are more likely to form complex ions.

Answer
Transition metals generally have higher ionisation energies compared to Group 1 metals and are indeed more likely to form complex ions due to their ability to form coordinate covalent bonds.
