FAQs on S & p block Elements Video Lecture - Chemistry for EmSAT Achieve

1. What are S & p block elements?
Ans. S & p block elements are the elements in the periodic table that belong to the S and P blocks. The S block elements are found in groups 1 and 2, while the P block elements are found in groups 13 to 18. These elements are characterized by their valence electron configuration and play a crucial role in various chemical reactions and biological processes.
2. How are S & p block elements different from each other?
Ans. S & p block elements differ from each other based on their electronic configurations and properties. The S block elements have valence electrons in the S orbital, while the P block elements have valence electrons in the P orbital. Additionally, S block elements are generally more reactive and metallic in nature, whereas P block elements exhibit a wider range of properties, including nonmetals, metals, and metalloids.
3. What are some examples of S & p block elements?
Ans. Examples of S block elements include hydrogen (H), lithium (Li), sodium (Na), and potassium (K) in Group 1, and beryllium (Be), magnesium (Mg), calcium (Ca), and strontium (Sr) in Group 2. Examples of P block elements include boron (B), carbon (C), nitrogen (N), and oxygen (O) in Group 13 to 16, and fluorine (F), chlorine (Cl), bromine (Br), and iodine (I) in Group 17.
4. How do S & p block elements contribute to the periodic table?
Ans. S & p block elements contribute to the periodic table by occupying different groups and periods. The S block elements are found in the first two groups, while the P block elements are spread across groups 13 to 18. Their arrangement in the periodic table helps in understanding periodic trends, such as atomic size, ionization energy, electronegativity, and chemical reactivity, which are important for predicting and explaining the behavior of elements.
5. What are the applications of S & p block elements in everyday life?
Ans. S & p block elements find various applications in everyday life. For example, S block elements like sodium and potassium are essential for maintaining electrolyte balance in the body and are used in the production of soaps, detergents, and fertilizers. P block elements like carbon and nitrogen are crucial components of organic compounds, which are the basis of life. Other applications include the use of boron in glass manufacturing and silicon in semiconductor devices.
