1. Element ‘B’ is likely to be ......... non-metallic in character than element‘A’.

Question

With reference to the elements of the modern periodic table.

Fill in the blanks with the appropriate word/s in each case.

1. Element ‘B’ is likely to be ......... non-metallic in character than element‘A’.

2. Element ‘Z’ in sub-group 2[IIA] is below element ‘Y’ in the same sub-group. The element ‘Z’ will be expected to have higher atomic size and ......... metallic character than ‘Y.

3. Argon in period 3 is likely to have a .......... atomic size than chlorine and its electron affinity value would be ......... compared to chlorine.

4. Across a period- Atomic size and metallic character .......... while I.P., E.A., E.N. and non-metallic character ........... and nuclear charge ............ Down a group-Atomic size and metallic character ..........while I.P., E.A., E.N. and non- metallic character ............. and nuclear charge increases.

Answer 1

1. Element ‘B’ is likely to be more non-metallic in character than element‘A’. 

2. Element ‘Z’ in sub-group 2[IIA] is below element ‘Y’ in the same sub-group. The element ‘Z’ will be expected to have higher atomic size and more metallic character than ‘Y’ 

3. Argon in period 3 is likely to have a larger atomic size than chlorine and its electron affinity value would be zero compared to chlorine. 

4. Across a period- Atomic size and metallic character decreases while I.P., E.A., E.N. and non-metallic character increases and nuclear charge increases. Down a group-Atomic size and metallic character increases while I.P., E.A., E.N. and non- metallic character decreases and nuclear charge increases.
