In my AQA textbook (Nelson Thornes) and revision guides it says Sc is not a transition metal yet when I look online and in online revision notes it says it is, was the definition of transition metals changed recently?

Transition metals have a partially filled d sub shell and form at least 1 ion with a incomplete d subshell (with copper and chromium being weird due to their structure for stability)
Scandium and Zinc do not do this but they are transition metals in a sense... But for your exam, Sc and Zn are he exceptions that they may ask you about,

Ohh okay because on the specification it says partially filled d sub shell in atoms or ions so doesn't Sc fit that definition? Or should I still assume it isn't for the exam?

know that transition metal characteristics of elements Ti – Cu arise from an incomplete d sub-level in atoms or ions
That doesn't define what one is. I haven't taught AQA for six years, but when I did, the definition was one that had an ion with an incomplete d sub-shell.
