FAQs on P Block Elements Mock Test 1-2 for JEE Main 2025-26 Preparation
1. What are p-block elements in the periodic table?
P-block elements are those elements in which the last electron enters the p-orbital of their outermost shell. They are located in groups 13 to 18 of the modern periodic table and include elements such as boron, carbon, nitrogen, oxygen, fluorine, and noble gases.
2. Which groups belong to the p-block in the periodic table?
The p-block elements are found in Groups 13 to 18 of the periodic table. This includes families such as boron family (Group 13), carbon family (Group 14), nitrogen family (Group 15), oxygen family (Group 16), halogens (Group 17), and noble gases (Group 18).
3. List three examples of p-block elements.
Three common examples of p-block elements are carbon (C), oxygen (O), and chlorine (Cl). These elements play essential roles in chemistry and biology and are commonly covered in Class 11 chemistry curriculum.
4. What are the general characteristics of p-block elements?
P-block elements display a wide range of properties including:
• Variable valency due to ns² np¹–⁶ configuration
• Presence of metals, non-metals, and metalloids
• Exhibit catenation (especially carbon and silicon)
• Show allotropic forms
• Increase in non-metallic character from left to right across a period
• High variation in electronegativity and ionization energy
5. Why do p-block elements show variable oxidation states?
Most p-block elements show variable oxidation states due to the involvement of both ns and np electrons, and sometimes inert pair effect. This effect is more pronounced as you move down a group, especially in heavier elements such as lead and tin.
6. What is the inert pair effect in p-block elements?
The inert pair effect refers to the tendency of the two s-electrons in the valence shell of heavier p-block elements to remain unshared or unbonded. This leads to the stability of lower oxidation states, especially in elements like lead (Pb) and thallium (Tl) in the p-block.
7. What are the chemical properties of Group 17 elements (halogens)?
Group 17 elements, also known as halogens, are highly reactive nonmetals. Their chemical properties include:
• High electronegativity and reactivity
• Formation of halide ions by gaining one electron
• React with metals to form ionic salts
• Powerful oxidizing agents
8. How do the physical properties of p-block elements vary across the period?
Within the p-block, metallic character decreases and non-metallic character increases from left to right. Atomic and ionic sizes decrease across the period, while ionization energy increases.
9. What are the uses of noble gases from the p-block?
Noble gases (Group 18) have several uses due to their inertness:
• Helium: Used in filling balloons, as a coolant in MRI scanners
• Neon: Used in advertising signs (neon lights)
• Argon: Used in electric bulbs and welding
• Krypton and xenon: Used in photographic flashes and high-intensity lamps
10. Why is catenation strongest in carbon among p-block elements?
Catenation, or the ability to form chains of the same element, is strongest in carbon due to its small atomic size and strong C–C covalent bonds. This property is less prominent in other p-block elements like silicon and tin.
11. What is the electronic configuration of p-block elements?
The valence shell electronic configuration of p-block elements is ns² np¹–⁶, where 'n' is the principal quantum number. The number of p-electrons (1–6) determines their position within the p-block.
12. Name three important compounds formed by p-block elements.
Three important compounds formed by p-block elements are:
• CO₂ (carbon dioxide) by carbon
• NH₃ (ammonia) by nitrogen
• H₂SO₄ (sulphuric acid) by sulphur
These compounds have wide industrial, biological, and environmental significance.
