CAPE Chemistry Unit 1 · 2008 · Paper 2 · Question 6(a)(ii)

This section covers the chemistry of elements, focusing on Period 3 elements and Group II elements. Table 3 provides atomic radii and melting points for Period 3 elements.

The trend in the melting points of the elements in Table 3 is related to structure and bonding. Describe the trend in the structure of the elements, and the trend in the bonding of the elements in Table 3.
