प्रश्न
Arrange the following as per the instruction given in the bracket:
Potassium, Lithium, Sodium (increasing order of ionization potential).
Advertisements
उत्तर
Potassium < Sodium < Lithium.
Explanation:
The ionization potential increases as we move up a group in the periodic table because the atomic size decreases, making it harder to remove an electron. Potassium, Lithium, and Sodium belong to Group 1 (alkali metals).
- Potassium (K): Has the lowest ionization potential because it has the largest atomic size and the outermost electron is farthest from the nucleus.
- Sodium (Na): Has a smaller atomic size than potassium, so its ionization potential is higher.
- Lithium (Li): Has the smallest atomic size and the strongest attraction between the nucleus and the outermost electron, giving it the highest ionization potential.
