FAQs on Short Tricks: s-block trends Video Lecture - Chemistry for JEE Main & Advanced

1. What are the trends observed in the s-block elements?

Ans. The trends observed in the s-block elements include increasing atomic radius down a group, decreasing ionization energy down a group, and increasing reactivity down a group.

2. How does the atomic radius change in the s-block elements?

Ans. The atomic radius generally increases down a group in the s-block elements. This is due to the addition of new energy levels as we move down the group.

3. What happens to the ionization energy in the s-block elements as we move down a group?

Ans. The ionization energy generally decreases down a group in the s-block elements. This is because the outermost electrons are farther away from the nucleus, making them easier to remove.

4. How does the reactivity change in the s-block elements?

Ans. The reactivity generally increases down a group in the s-block elements. This is because the outermost electrons are farther away from the nucleus, making them more easily lost or shared in chemical reactions.

5. Are there any exceptions to the trends observed in the s-block elements?

Ans. Yes, there are some exceptions to the trends observed in the s-block elements. For example, the ionization energy of helium is higher than that of hydrogen, even though helium is below hydrogen in the periodic table. This is because helium has a completely filled 1s orbital, which provides extra stability and makes it harder to remove an electron.
