Which element is similar in properties to sulphur?
Think it through first, then pick an option.
- a N
- b C
- c Si
- d O
Answer and explanation
Correct answer: d O
O and S are both in group 16, so their properties are alike.
Why the other options are wrong
- a N: N is in group 15, not sulphur's group. The answer is O.
- b C: C is in group 14. The answer is O: O and S are both in group 16, so their properties are alike.
- c Si: Si is in group 14 and in S's period, not its group. The answer is O.
