Typical Properties of Transition Metals (Edexcel GCSE Chemistry): Flashcards

Central block, groups 3 to 12

Iron ($Fe$), copper ($Cu$), gold ($Au$)

High melting and boiling points

High density - heavy for their size

Excellent conductors of heat and electricity

Can be hammered/rolled into thin sheets

Can be drawn into wires

Blue or green

Used as catalysts to speed up reactions

Catalyst to make ammonia

Can lose different numbers of electrons

$Fe^{2+}$ (iron II) and $Fe^{3+}$ (iron III)

Less reactive than alkali metals
