FAQs on Quick Revision: The p-Block Elements - Chemistry Class 11 - NEET
|1. What are the properties of p-block elements?
Ans. P-block elements are characterized by their valence electron configuration in the p orbital. They exhibit a wide range of properties, including varying chemical reactivity, ability to form multiple oxidation states, and participation in covalent bonding. They are also known for their diverse physical properties, such as varying melting and boiling points, electrical conductivity, and solubility.
|2. How are p-block elements classified?
Ans. P-block elements are classified into three categories based on their electron configuration: group 13 elements (Boron, Aluminum, Gallium, Indium, and Thallium), group 14 elements (Carbon, Silicon, Germanium, Tin, and Lead), and group 15 elements (Nitrogen, Phosphorus, Arsenic, Antimony, and Bismuth). These groups are also referred to as Group IIIA, Group IVA, and Group VA, respectively.
|3. What are the applications of p-block elements?
Ans. P-block elements have numerous applications in various fields. For example, Boron is used in the production of fiberglass, ceramics, and semiconductors. Silicon is a key component in the semiconductor industry and is used extensively in electronic devices. Nitrogen is essential for the production of fertilizers, while Phosphorus is used in the manufacturing of detergents and matches. Antimony finds applications in the production of flame retardants and alloys.
|4. How do p-block elements form covalent bonds?
Ans. P-block elements form covalent bonds by sharing electrons with other atoms. Since p-block elements have valence electrons in the p orbital, they can participate in bonding by overlapping their p orbitals with other atoms. This sharing of electrons results in the formation of covalent bonds, allowing p-block elements to form molecules and compounds.
|5. What is the significance of the p-block elements in the periodic table?
Ans. P-block elements are of great significance in the periodic table as they occupy a large portion of it. They contribute to the diversity of chemical and physical properties exhibited by elements. The p-block elements also play a crucial role in various biological processes, such as the presence of phosphorus in DNA and the involvement of nitrogen in protein synthesis. Additionally, the p-block elements have a wide range of industrial applications, making them economically important.
