Zinc Ionic Charge and Bonding Concepts

The video tutorial explores the ionic charge of zinc (Zn). Initially, zinc is neutral on the periodic table, with equal protons and electrons. However, zinc is unique among transition metals as it consistently forms ions with a 2+ charge by losing two electrons. This process is explained through zinc's interaction with chlorine, where zinc loses electrons to form Zn2+ ions, and chlorine gains electrons to form Cl- ions, resulting in the compound zinc chloride (ZnCl2). The video also distinguishes between ionic charge and oxidation number, noting their overlap.

What is the charge of zinc when it is in its elemental form on the periodic table?
