The correct decreasing order of electropositive character among the following elements is ;
Fe, Sc, Rb, Br, Te, F, Ca
(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: (d)
Explanation: Rb > Ca > Sc > Fe > Te > Br > F

Group/CategoryElementElectropositive CharacterNote
Alkali MetalsRbVery High Alkali and alkaline earth metals are most electropositive.
Alkali metals are more electropositive than

D-block near alkaline earth metalsScHigh In d-block series, the. elements near alkaline earth
metals are more electropositive than rest of the
members.
D-block not near alkaline earth metalsFeModerate In d-block series, the. elements near alkaline earth
metals are more electropositive than rest of the
members.
MetalloidsTeModerate Metalloids are less electropositive than metals.
HalogensBrLow Halogens (Non-metals) are least electropositive. In
halogen group, electropositive character increases as
atomic number increases.
