A sample from this course
One topic, as StudyPath teaches it.
Write the electronic configuration of the 1st row transition elements
To master this topic, you need to know the electronic configurations of the first-row transition elements from Scandium to Zinc and understand how electrons fill the 3d and 4s subshells. This is important in exams because questions often test both the correct configurations and the special exceptions, especially chromium and copper.
