Which statement is true regarding melting points when comparing Group 1 and transition metals?

Transition metals are known for their generally higher melting points compared to Group 1 metals, which is why this statement is true. The structure of transition metals contributes to their elevated melting points; they have a strong metallic bonding due to the presence of d-electrons that can contribute to bonding. This results in a more complex and stable crystal lattice structure, leading to stronger interactions between the metal ions and the delocalized electrons.

In contrast, Group 1 metals, also known as alkali metals, have relatively low melting points. They possess only one valence electron that can be easily lost, resulting in weaker metallic bonds compared to those found in transition metals. This difference in atomic structure and bonding strength explains why transition metals typically exhibit much higher melting points than Group 1 metals.
