The correct decreasing order of electropositive character among the following elements is
A
Fe > Sc > Rb > Br > Te > F > Ca
B
Ca > Rb > Sc > Fe > Te > F > Br
C
Rb > Ca > Sc > Fe > Br > Te > F
D
Rb > Ca > Sc > Fe > Te > Br > F
Answer
Rb > Ca > Sc > Fe > Te > Br > F
Explanation
Solution
Alkali and alkaline earth metals are most electropositive. Alkali metals are more electropositive than alkaline earth metals. In d-block elements , the elements near the alkaline earth metals are more electropositive than rest of the members. Metalloids are less electropositive than metals. Halogens (nonmetals) are least electropositive. In halogen group electropositive character increases down the group.
