(i) Noble gases
(ii) D2SO4
(iii) (a) Y
(b) E
(iv) Ionic bond – Because B reacts by losing an electron (s) which are gained by H.
(v) D//M
(vi) Because E reacts by gaining an extra electron which reducethe electrostatic
pull by the positive nucleus making the ionic radius increase.
(vii) At Period III Group IV
(viii) Because of the increase in the strength of the molecular bonds in the oxide of L as
compared to that of G.
(ix) C has a smaller atomic radius than I because of the increase in the strength of the
nucleus on the valency electrons in C as the number of protons increase
(x) 1st ionization energies increases from J – L across the period due to addition of an
extra proton in the nucleus increasing the attraction of the valency electrons
