The correct decreasing order of electropositive character among the following elements is:
Fe, Sc, Rb, Br, Te, F, Ca

A

Fe gt Sc gt Rb gt Br gt Te gt F gt Ca

B

Ca gt Rb gt Sc gt Fe gt Te gt F gt Br

C

Rb gt Ca gt Sc gt Fe gt Br gt Te gt F

D

Rb gt Ca gt Sc gt Fe gt Te gt Br gt F

Text Solution

Verified by Experts

The correct Answer is:
D
Remember the following points:
(i) Alkali and alkaline earth metals are most electropositive. Alkali metals are more electropositive than alkaline earth metals.
(ii) In d-block series, the elements near alkaline earth metals are more electropositive than rest of the members.
(iii) Metalloids are less electropositive than metals.
(iv) Halogens (Non-metals) are least electropositive. In halogen group, electropositive character increases as atomic number increases.
