313286 Elements which have relatively high ionisation energy and occur as sulphides are

1 halogens
2 transition elements
3 alkali metals
4 metalloids.
CHXI03:CLASSIFICATION OF ELEMENTS AND PERIODICITY IN PROPERTIES

313287 Assertion :
The highest I.E. in a period is shown by noble gas.
Reason :
Noble gases are at the extreme right of the period.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.

\({\rm{A}} \to {{\rm{A}}^{\rm{ + }}}{\rm{ + }}{{\rm{e}}^{\rm{ - }}}{\rm{;}}{{\rm{E}}_{\rm{1}}}\,\,{\rm{and}}\,{{\rm{A}}^{\rm{ + }}} \to {{\rm{A}}^{{\rm{2 + }}}}{\rm{ + }}{{\rm{e}}^{\rm{ - }}}{\rm{;}}\,{{\rm{E}}_{\rm{2}}}\)
The energy required to pull out the two electrons are \({{\rm{E}}_{\rm{1}}}\,\,{\rm{and}}\,\,{{\rm{E}}_{\rm{2}}}\) respectively. The correct relationship between two energies would be

1 \({{\rm{E}}_{\rm{1}}}{\rm{ < }}\,{{\rm{E}}_{\rm{2}}}\)
2 \({{\rm{E}}_{\rm{1}}}{\rm{ = }}\,{{\rm{E}}_{\rm{2}}}\)
3 \({{\rm{E}}_{\rm{1}}}{\rm{ > }}\,{{\rm{E}}_{\rm{2}}}\)
4 \({{\rm{E}}_{\rm{1}}} \ge \,{{\rm{E}}_{\rm{2}}}\)
