Typical Properties of Transition Metals Flashcards

All 7 cards in this deck

Where are the transition elements found in the periodic table?

In the central block, between Group 2 and Group 3.

Name the six transition metals used as examples in the specification.

Chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni) and copper (Cu).

State three typical chemical properties of many transition metals.

They form ions with different charges, they form coloured compounds, and they are useful as catalysts.

An element R forms ions with the formulae $R^{2+}$ and $R^{3+}$. What type of element is R most likely to be?

A transition metal, because transition metals form ions with different charges.

e.g. iron forms $Fe^{2+}$ and $Fe^{3+}$

True or false? Most transition metals form colourless compounds.

False. Transition metals form coloured compounds.

e.g. copper(II) sulfate solution is blue

What are the steps to pick out the metal in a list that is most likely to act as a catalyst?

e.g. aluminium (Al), barium (Ba), potassium (K), vanadium (V)

1. Find each metal in the periodic table.
2. Look for one in the central block between Group 2 and Group 3 — vanadium.
3. Answer that transition metal: vanadium (V).

True or false? Cobalt is a transition element, so a solution containing $\mathrm{Co^{2+}}$ ions is likely to be coloured.

True. Transition metals such as cobalt form coloured compounds and coloured solutions.
