Solved 2018 Question Paper ICSE Class 10 Chemistry — Question 2
Back to all questionsIn Period 3 of the Periodic Table, element B is placed to the left of element A.
On the basis of this information, choose the correct word from the brackets to complete the following statements:
(i) The element B would have (lower / higher) metallic character than A.
(ii) The element A would probably have (lesser / higher) electron affinity than B.
(iii) The element A would have (greater / smaller) atomic size than B.
If the element are placed as B and then A in the 3rd period of the periodic table then
(i) The element B would have higher metallic character than A as metallic character decreases across a period.
(ii) The element A would probably have higher electron affinity than B as electron affinity increases across a period.
(iii) The element A would have smaller atomic size than B as atomic size decreases across a period.
