Worked Solution & Example Answer:In comparison with Group 1 metals, transition metals in the same period as Group 1 metals tend to A - VCE - SSCE Chemistry - Question 4 - 2002 - Paper 1
Step 1
Step 2
B. have a higher melting temperature and a larger atomic radius.
Answer
This statement is correct. Transition metals usually exhibit higher melting points compared to Group 1 metals due to their stronger metallic bonding. They also have a larger atomic radius due to the increased number of electron shells.
Step 3
C. be more easily oxidised and display variable oxidation states.
Answer
This statement is inaccurate for transition metals. While they can display variable oxidation states, they are generally not more easily oxidised than Group 1 metals, which have a more straightforward oxidation process.
Step 4
D. have lower ionisation energy and are more likely to form complex ions.
Answer
This statement is also incorrect. Transition metals have higher ionisation energies compared to Group 1 metals and are known to form complex ions due to the presence of d electrons, but this is not necessarily related to lower ionisation energy.
