General trends across Groups 13 to 18 MCQs with solutions
10 of the 12 published questions on this topic, exactly as they appear in a test. Answers and worked solutions come with your result rather than on this page.
Across a period from Group 13 toward Group 18, atomic size generally
- A. decreases
- B. increases
- C. remains exactly constant
- D. first doubles then becomes zero
Down a p-block group, atomic radius generally
- A. increases
- B. decreases continuously
- C. remains identical
- D. becomes zero
Across a period, first ionisation enthalpy generally tends to
- A. increase, with some exceptions
- B. decrease uniformly
- C. remain zero
- D. be independent of nuclear charge
Across a p-block period, metallic character generally
- A. decreases from left to right
- B. increases from left to right
- C. remains constant
- D. is absent in every group
Which element is expected to be more metallic: Al or Cl?
- A. Al
- B. Cl
- C. They are identical
- D. Neither has any metallic character
Which trend is most reasonable down Group 17 from F to I?
- A. Atomic size increases
- B. Atomic size decreases
- C. Electronegativity increases strongly
- D. Ionisation enthalpy increases strongly
Which statement is most consistent with Group 18 trends?
- A. Noble gases have filled valence shells and generally high ionisation enthalpies
- B. They readily lose one electron like alkali metals
- C. They are strongly metallic at the top of the group
- D. They have seven valence electrons
Moving from Group 13 to Group 17 in the same period, the common tendency toward non-metallic behaviour generally
- A. increases
- B. decreases
- C. remains exactly unchanged
- D. vanishes after Group 14
Which pair correctly states a general down-group trend in the p-block?
- A. Atomic size increases and ionisation enthalpy generally decreases
- B. Atomic size decreases and ionisation enthalpy increases
- C. Both size and ionisation enthalpy increase sharply
- D. Both are exactly constant
Why do oxides generally become more acidic across a p-block period from metallic to non-metallic elements?
- A. Increasing non-metallic character favours covalent acidic oxides
- B. Atomic size alone makes every oxide basic
- C. All oxides become ionic toward Group 18
- D. Oxidation state always falls across a period
Common mistakes in General trends across Groups 13 to 18
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Treats increasing nuclear charge as the only factor and ignores added shells and shielding.
- Focuses on increasing nuclear charge alone and predicts both a smaller radius and higher ionisation enthalpy down the group.
