FAQs on The p-Block Elements in One Shot (NCERT) Video Lecture - Chemistry Class 12 - NEET

1. What are the p-block elements in the periodic table?
Ans. The p-block elements in the periodic table are the elements found in groups 13 to 18. These elements have their valence electrons in the p orbital of their outermost energy level.
2. What are the properties of p-block elements?
Ans. The properties of p-block elements include: - They are generally nonmetals, metalloids, and some metals. - They exhibit a wide range of chemical reactivity. - They show diverse oxidation states. - They can form covalent compounds. - They have variable atomic sizes and ionization energies.
3. What are the common uses of p-block elements?
Ans. The p-block elements have various uses in different industries and applications. Some common uses include: - Carbon (C) is used in the production of steel, fuels, and various organic compounds. - Nitrogen (N) is used in fertilizers, explosives, and as a coolant in certain industries. - Oxygen (O) is essential for respiration and combustion processes. - Silicon (Si) is used in the production of computer chips and solar cells. - Phosphorus (P) is used in fertilizers, detergents, and matches.
4. How do p-block elements react with other substances?
Ans. The reactivity of p-block elements depends on their position in the periodic table. Nonmetals in the p-block tend to gain electrons to achieve a stable electron configuration, while metals in the p-block tend to lose electrons. They can form both ionic and covalent compounds with other elements.
5. What are some important compounds formed by p-block elements?
Ans. Some important compounds formed by p-block elements include: - Carbon dioxide (CO2) is a compound formed by carbon and oxygen. - Water (H2O) is a compound formed by hydrogen and oxygen. - Ammonia (NH3) is a compound formed by nitrogen and hydrogen. - Silicon dioxide (SiO2) is a compound formed by silicon and oxygen. - Sulfuric acid (H2SO4) is a compound formed by sulfur, hydrogen, and oxygen.
