Question:
Cerium (IV) has a noble gas configuration. Which of the following is correct statement about it?
Cerium (IV) has a noble gas configuration. Which of the following is correct statement about it?
Updated On: Jul 6, 2024
- It will not prefer to undergo redox reactions.
- It will prefer to gain electron and act as an oxidizing agent
- It will prefer to give away an electron and behave as reducing agent
- It acts as both, oxidizing and reducing agent.
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
\(E°\) value of \(Ce^{+4}|Ce^{+3}\) is \(1.74\ V\), which suggests that it is a very good oxidising agent.
So, the correct option is (B): It will prefer to gain electron and act as an oxidizing agent.

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
