(a)
Interpretation:
The element which is most metallic should be selected from the Bi, S, Ba, As and Ca.
Concept introduction:
The most metallics are present in the left corner of the periodic table.
(b)
Interpretation:
The element which is most nonmetallic should be selected from the Bi, S, Ba, As and Ca.
Concept introduction:
the most nonmetallic are present in the right corner of the periodic table.
(c)
Interpretation:
The element which has the intermediate value when the five are arranged in order of increasing 1st ionization energy should be selected from the Bi, S, Ba, As and Ca.
Concept introduction:
Ionization energies generally increase from left to right across the period and decreasing from top to bottom within a group.
