FAQs on P-Block Elements Trends: Metallic Character Video Lecture - Chemistry Class 11 - NEET

1. What is metallic character in p-block elements?
Ans. Metallic character refers to the ability of an element to exhibit metallic properties, such as luster, malleability, ductility, and electrical conductivity. In p-block elements, metallic character generally decreases from left to right across a period and increases down a group.
2. Which p-block elements have the highest metallic character?
Ans. The p-block elements at the bottom left of the periodic table, such as the alkali metals (Group 1) and alkaline earth metals (Group 2), have the highest metallic character among the p-block elements. These elements readily lose electrons to form positive ions, which contributes to their metallic behavior.
3. How does atomic size affect the metallic character of p-block elements?
Ans. Atomic size plays a significant role in determining the metallic character of p-block elements. As we move from left to right across a period, the atomic size decreases due to increased nuclear charge, leading to stronger attraction between the electrons and the nucleus. This decrease in atomic size reduces metallic character. Conversely, as we move down a group, the atomic size increases, resulting in enhanced metallic character.
4. What is the trend of metallic character in p-block elements?
Ans. The metallic character in p-block elements generally decreases across a period from left to right and increases down a group. This trend is primarily influenced by factors such as atomic size, ionization energy, and electron affinity.
5. How does the number of valence electrons impact the metallic character of p-block elements?
Ans. The number of valence electrons greatly affects the metallic character of p-block elements. Elements with fewer valence electrons, such as metals, tend to have higher metallic character as they readily lose electrons to form positive ions. Conversely, elements with more valence electrons, such as nonmetals, exhibit lower metallic character as they have a higher tendency to gain electrons and form negative ions.
