FAQs on Quick Revision: The p-Block Elements - Chemistry Class 12 - NEET

1. What are p-block elements in NEET?
Ans. p-block elements in NEET refer to a group of elements in the periodic table that belong to groups 13 to 18. These elements have their outermost electron in the p orbital. They include elements such as Boron, Carbon, Nitrogen, Oxygen, Fluorine, and others.
2. What are the properties of p-block elements?
Ans. The properties of p-block elements include their ability to form covalent bonds, exhibit a wide range of oxidation states, and show both metallic and non-metallic behavior. They also have various atomic sizes, electronegativities, and ionization energies depending on their position in the periodic table.
3. How are p-block elements classified in NEET?
Ans. p-block elements in NEET are classified into three categories based on their electronic configurations and properties. These categories are Group 13 elements (Boron family), Group 14 elements (Carbon family), and Group 15-18 elements (Nitrogen, Oxygen, Halogens, and Noble gases).
4. What are the uses of p-block elements?
Ans. p-block elements have numerous applications in various industries. For example, Boron is used in the production of borosilicate glass and as a dopant in semiconductors. Carbon is the basis of organic chemistry and is present in countless compounds. Nitrogen is used in fertilizer production, and Noble gases are used in lighting and cryogenics.
5. How do p-block elements contribute to environmental pollution?
Ans. Certain p-block elements like Nitrogen and Phosphorus can contribute to environmental pollution. Nitrogen compounds released from agricultural activities or industrial emissions can cause water pollution and contribute to the formation of smog. Phosphorus compounds from fertilizers can also lead to excessive nutrient enrichment in water bodies, resulting in harmful algal blooms.
