Question:
The element with the lowest ionization potential is
The element with the lowest ionization potential is
Updated On: May 15, 2024
- Na
- K
- Rb
- Cs
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
lonisation potential is the amount of energy required to remove an electron from an isolated gaseous atom. Since, on moving down the group, the size of atom increases, thus the outer electron gets farther and farther away from the nucleus and hence, the less amount of energy is required to remove it. Thus, ionisation potential decreases and hence, $Cs$ has lowest ionisation potential.

Haloalkanes and Haloarenes - Classification
Classification of Haloalkanes and Haloarenes are as follows:
Haloalkanes and Haloarenes are Classified on the Basis of the Number of Halogen Atoms:
These are further classified as mono, di, or polyhalogen (tri-,tetra-, etc.) compounds depending on whether they contain one, two or more halogen atoms in their structures. For example;
- Monohaloalkane
- Dihaloalkane
- Trihaloalkane
Haloalkanes and Haloarenes are Classified on Compounds Containing sp3 C—X Bond (X= F, Cl, Br, I)
This class includes:
- Alkyl halides or haloalkanes (R—X)
- Allylic halides
- Benzylic halides
Haloalkanes and Haloarenes are Classified on Compounds Containing sp2 C—X Bond
This class includes:
- Vinylic halides
- Aryl halides
