Question

Which order of relative size amongst the following is incorrect?
A)Li < Na < K
B)C < Si < Al
C)Mg > Al < Na
D)F < Cl < Br

Quizplus · Accepted Answer

The correct order of relative size for the elements mentioned in option C should be Mg < Al < Na, based on their positions in the periodic table. As we move down a group in the periodic table, atomic size increases, and as we move from left to right across a period, atomic size decreases. Mg and Al are in the same period with Mg being to the left of Al, making Mg smaller than Al. Na is in the period below Al, making it larger than both Mg and Al.
