FAQs on Question Bank (Solutions): The s-Block Elements - Chemistry for JEE Main & Advanced

1. What are s-block elements in the periodic table?
Ans. The s-block elements in the periodic table are the elements found in Group 1 (alkali metals) and Group 2 (alkaline earth metals). They are called s-block elements because the last electron enters the s-orbital of their outermost energy level.
2. What are some common properties of s-block elements?
Ans. Some common properties of s-block elements include low ionization energies, high reactivity, and the tendency to lose electrons to form positive ions. They are typically soft metals, have low melting and boiling points, and are good conductors of heat and electricity.
3. Why are alkali metals highly reactive?
Ans. Alkali metals, which are found in Group 1 of the periodic table, are highly reactive due to their low ionization energies. They readily lose their outermost electron to achieve a stable electron configuration, resulting in the formation of a positive ion. This reactivity increases as you move down the group.
4. What are some important uses of alkaline earth metals?
Ans. Alkaline earth metals, found in Group 2 of the periodic table, have various important uses. For example, magnesium is used in the production of lightweight alloys and as a component in fireworks. Calcium is essential for the formation of bones and teeth in humans, while barium is used in X-ray imaging.
5. How do s-block elements differ from p-block elements?
Ans. S-block elements differ from p-block elements in terms of their electron configurations. S-block elements have their outermost electron in the s orbital, while p-block elements have their outermost electron in the p orbital. This difference in electron configuration leads to variations in their chemical properties and reactivity.
