The electronic configuration of Praseodymium (Pr) is-

• A. [54Xe]4f₂5d₁6s²
• B. [54Xe]4f₁5d₂6s²
• C. [54Xe]4f₃6s²
• D. [54Xe]4f₃5d₂

The electronic configuration of Praseodymium (Pr) is an important aspect of its chemistry. Praseodymium has an atomic number of 59, which means it has 59 electrons. The correct electronic configuration is:

Correct Answer

C. [54Xe] 4f³ 6s²

Explanation of the Configuration

• [54Xe] represents the electron configuration of Xenon, which accounts for the first 54 electrons.
• The 4f³ indicates that there are three electrons in the 4f subshell.
• 6s² shows that there are two electrons in the 6s subshell.

This configuration reflects the distribution of electrons in Praseodymium, which is a lanthanide element. Understanding these configurations helps in predicting the element's chemical behavior and properties.
