FAQs on P-Block Elements Trends: Atomic Radii Video Lecture - Chemistry Class 11 - NEET
| 1. What are p-block elements? |  |
Ans. P-block elements are the elements in the periodic table that belong to groups 13 to 18. These elements have their valence electrons in the p orbital of the outermost energy level. They include metals, nonmetals, and metalloids.
| 2. How does atomic radius change across the p-block elements? | |
Ans. The atomic radius generally decreases across the p-block elements from left to right in a period. This is due to the increase in effective nuclear charge, which attracts the electrons more strongly, causing the atomic size to decrease. However, the atomic radius increases down a group due to the addition of new energy levels.
| 3. Why does atomic radius increase down a group in the p-block elements? | |
Ans. The atomic radius increases down a group in the p-block elements because new energy levels are added as you move down the group. These additional energy levels lead to an increase in the size of the electron cloud, resulting in an increase in atomic radius.
| 4. How does the atomic radius of p-block elements compare to s-block elements? | |
Ans. Generally, the atomic radius of p-block elements is smaller than that of s-block elements. This is because p-block elements have a higher effective nuclear charge due to their higher atomic number. The increased nuclear charge attracts the electrons more strongly, resulting in a smaller atomic radius compared to s-block elements.
| 5. What factors affect the atomic radius of p-block elements? | |
Ans. The atomic radius of p-block elements is mainly influenced by the effective nuclear charge and the number of energy levels. As the effective nuclear charge increases, the atomic radius decreases. Conversely, as the number of energy levels increases, the atomic radius increases. Additionally, electron-electron repulsion can also affect the atomic radius.
