Revise: Comparison with Alkali MetalsTransition metals generally have higher melting points than Group 1 metals. A transition metal therefore usually needs much more heating before its solid structure breaks down and it becomes a liquid. Iron, for example, melts at a far higher temperature than sodium.
Make every comparison directional: write that transition metals have higher melting points or densities than Group 1 metals, rather than merely saying that the values are “different”.
For reactivity questions, compare the same reagent on both sides: transition metals are less reactive than Group 1 metals with water, oxygen and halogens.
