The grid below represents part of the periodic table. Study it and answer the
questions that follow. (The letters are not the actual symbols of the elements)

i) Select the element in period three which has the shortest atomic radius. Give a reason
for your answer.
ii) Using dots (.) and crosses (x) to represent outermost electrons, draw a diagram to
show the bonding in the compound formed when chlorine reacts with element X
iii) When three liters of chlorine gas were completely reacted with element Y, 11.85g of
the product were formed. Calculate the relative atomic mass of element Y
(R.A.M of chlorine = 35.5, molar gas volume = 24 liters)
