Worked practice questions

Which element heads group 15 of the periodic table?

  1. Nitrogen
  2. Antimony
  3. Bismuth
  4. Arsenic
Show answer and solution

Correct answer: A. Nitrogen

1. Group 15 runs from the lightest member downwards. 2. The list opens with nitrogen and phosphorus. 3. So nitrogen heads the group. _Source: syllabus Chemistry, Chapter 7, The p-Block Elements._

Going down group 15, the character shifts from non-metallic to:

  1. Acidic one
  2. Metallic
  3. Gaseous
  4. Ionic one
Show answer and solution

Correct answer: B. Metallic

1. The lighter members behave as non-metals. 2. The heavier ones behave as metals. 3. So the shift is from non-metallic to metallic. _Source: syllabus Chemistry, Chapter 7, The p-Block Elements._

In group 15, arsenic and antimony are classed as:

  1. Metalloids
  2. Non-metals
  3. True metals
  4. Noble gases
Show answer and solution

Correct answer: A. Metalloids

1. Nitrogen and phosphorus are non-metals. 2. Bismuth is a typical metal. 3. Arsenic and antimony sit between as metalloids. _Source: syllabus Chemistry, Chapter 7, The p-Block Elements._
