Explanation / Answer
Q7)
a) Going from left to right in the periodic table, the metallic character decreases since the first group contains alkaline metals, second contains alkaline earth metals followed by d block metal and then anion and in the last group inert gases.
Hence the elements become less metallic from left to right
b) Going from top to bottom, there is an increase in ionic character seen which will increase the metallic strength of the metal, hence the elements become more metallic from top to down
Q8)
X2(g) + 2Y-(aq) ------- 2X-(aq) + Y2(g)
The order of reactivity in halogen group is I < Br < Cl < F, so a more reactive halogen in this case X2 will displace a less reactive one
Q9)
a) So the generated Y2 must be Cl2(g). The Cl2(g) gas will only be generated when X2 is F2(g), since F is more reactive than Cl
b) We can use any non-polar solvent for this reaction i.e. gasoline etc
c) For alkaline earth metals, the flame test is used by throwing the salt in frame and the color ignition will provide an hint which metal is been used in the salt
