Zinc Electron Configuration Concepts

The video tutorial covers the electron configuration of zinc, starting with its common oxide form, ZnO. It explains how to identify zinc on the periodic table and write its electron configuration using argon as a reference. The tutorial also delves into the nuances of electron removal during zinc oxidation, highlighting the role of 4s electrons. The video provides a comprehensive understanding of zinc's electron configuration and oxidation process.

What is the significance of the 3d subshell in zinc's electron configuration?

• It is not filled in zinc

• It is filled simultaneously with 4s

• It is filled after 4s

• It is filled before 4s

Which subshell's electrons are most likely to be removed when zinc is oxidized?

• 3d

• 4s

• 4p

• 5s

Why are 4s electrons removed before 3d electrons in zinc?

• 3d electrons are more reactive

• 3d electrons are in a lower energy level

• 4s electrons have higher energy

• 4s electrons are closer to the nucleus

What is the role of the 4s subshell in the oxidation of zinc?

• It transfers electrons to 3d

• It remains unchanged

• It loses electrons

• It gains electrons
