Worked practice questions

On the periodic table, what is a vertical column of elements called?

  1. A period
  2. A block
  3. A shell
  4. A group
Show answer and solution

Correct answer: D. A group

1. Elements were arranged so that similar properties fall into the same vertical column. 2. A group is a column on the periodic table containing elements with similar properties. 3. A period is the horizontal row, so the two words must not be swapped. _Source: Siyavula Physical Sciences Grade 10 (Everything Science, CC BY 4.0), Chapter 5: The periodic table_

What happens to the atomic radius as you move across a period from left to right?

  1. It increases
  2. It stays fixed
  3. It decreases
  4. It doubles
Show answer and solution

Correct answer: C. It decreases

1. Moving across a period adds protons to the nucleus while filling the same energy level. 2. The stronger positive pull draws the electron cloud in tighter. 3. The atomic radius therefore decreases across a period. 4. Ionisation energy and electronegativity move the other way and increase across a period. 5. Down a group the pattern flips, since the atomic radius increases. _Source: Siyavula Physical Sciences Grade 10 (Everything Science, CC BY 4.0), Chapter 5: The periodic table_
