Which graph correctly shows relative electronegativity plotted against relative atomic radius for the elements Na, Mg, Al and Si?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
AGraph showing points such that atomic radius increases from left to right on x-axis and electronegativity increases from bottom to top on y-axis, with Si bottom-left and Na top-right.
BGraph showing points such that atomic radius increases from left to right on x-axis and electronegativity decreases from top to bottom on y-axis, with Si top-left and Na bottom-right.
CGraph showing points such that atomic radius increases from left to right on x-axis and electronegativity increases from bottom to top on y-axis, with Na bottom-left and Si top-right.
DGraph showing points such that atomic radius increases from left to right on x-axis and electronegativity decreases from top to bottom on y-axis, with Si bottom-left and Na top-right.
✓ Correct answer
B: Graph showing points such that atomic radius increases from left to right on x-axis and electronegativity decreases from top to bottom on y-axis, with Si top-left and Na bottom-right.
