Electron Configuration Exceptions in Transition Metals

This video tutorial explores exceptions to the general pattern of electron configurations, focusing on chromium, manganese, copper, and silver. It explains why these elements deviate from expected configurations and how their electron arrangements lead to greater stability. The video also provides links to additional resources for further understanding.

What is the main focus of the video regarding electron configurations?

• History of the periodic table

• General pattern of electron configurations

• Chemical reactions involving electrons

• Exceptions to the general pattern

Why are chromium and mnium considered exceptions in electron configurations?

• They have more electrons than expected

• Their d orbitals are half-filled for stability

• They have fewer protons than expected

• Their s orbitals are completely filled

What change occurs in the electron configuration of chromium to achieve stability?

• An electron is moved from the 3d to the 4s orbital

• An electron is moved from the 4s to the 3d orbital

• An electron is removed from the 3d orbital

• An electron is added to the 4s orbital

What is the electron configuration of chromium after adjustment?

• 3d4 4s2

• 3d5 4s1

• 3d6 4s0

• 3d3 4s3

What is the main reason for the electron configuration exception in copper and silver?

• Fully filled d orbitals

• Empty f orbitals

• Partially filled p orbitals

• Half-filled s orbitals

How does the electron configuration of copper change to achieve stability?
