Transition Metals vs. Alkali Metals Flashcards

All 6 cards in this deck

How do the melting points of the transition metals compare with those of the Group 1 metals?

Transition metals have higher melting points (Group 1 metals have lower melting and boiling points).

How do the densities of the transition metals compare with those of the Group 1 metals?

Transition metals have higher densities; Group 1 metals have low densities.

How do the strength and hardness of the transition metals compare with those of the Group 1 metals?

Transition metals are stronger and harder; Group 1 metals are softer.

e.g. iron is hard, but sodium can be cut with a knife

How does the reactivity of the transition metals with oxygen, water and halogens compare with that of the Group 1 metals?

Transition metals are less reactive — they react much more slowly, or not at all, with oxygen, water and halogens.

True or false? Iron reacts vigorously with cold water in the same way as sodium does.

False. Transition metals such as iron react very slowly or not at all with cold water, unlike Group 1 metals.

True or false? Group 1 metals are widely used as catalysts.

False. It is the transition metals that are useful as catalysts.
