Transition metals
Transition metals
The first d-block series runs from scandium to zinc, forming part of the central block of the periodic table between Group 2 and Group 3. However, zinc is not classified as a transition element under the definition that requires an incomplete d subshell, because Zn2+^{2+}2+ has a full d subshell. Examples of transition metals include iron, copper, nickel, chromium, manganese, silver and gold.
Step-by-step lessons on Edexcel GCSE Chemistry 6.1 Transition metals, alloys and corrosion, covering 6.1.1 Properties of transition metals, 6.1.2 Corrosion and its prevention, and 6.1.3 Alloys and the uses of metals. Each one builds up to exam-style questions. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
