d Block Elements : Introduction

The video tutorial introduces D block elements, explaining their electron configurations and why they are termed transition metals. It covers the IUPAC definition of transition metals, highlighting the incomplete D subshell. The tutorial also discusses anomalies in electronic configurations, such as those of chromium and copper, due to stability factors. Group 12 elements, despite having full D10 configurations, are not considered transition metals but are studied alongside them. The video concludes with an invitation to explore the characteristics and trends of transition elements.

Explain why potassium and calcium have their valence electrons in the 4S orbital instead of the 3D orbital.
