Worked practice questions

p-block elements are those whose:

  1. f-orbital filled
  2. DIFFERENTIATING electron enters the p-subshell (groups 13-18)
  3. s-electron is the differentiating electron
  4. d-orbital filled
Show answer and solution

Correct answer: B. DIFFERENTIATING electron enters the p-subshell (groups 13-18)

p-block: groups 13–18. Includes boron family (group 13), carbon family (14), nitrogen family (15), oxygen family (16), halogens (17), noble gases (18). Last electron in p-orbital.

Group 17 elements are called:

  1. Halogens
  2. Chalcogens
  3. Alkali metals
  4. Noble gases
Show answer and solution

Correct answer: A. Halogens

**Group 17:** F, Cl, Br, I, At — halogens (Greek 'salt-formers'). Diatomic molecules. Highly reactive nonmetals. Form -1 ions easily.

Most electronegative element in periodic table:

  1. F (fluorine, 4.0 on Pauling scale)
  2. N
  3. O
  4. Cl
Show answer and solution

Correct answer: A. F (fluorine, 4.0 on Pauling scale)

F is most electronegative (Pauling scale 4.0). **Other high values:** O (3.5), N (3.0), Cl (3.0). Decreasing across period? No — F highest. Increases left to right, decreases top to bottom.
