Q. The correct decreasing order of electropositive character among the following elements is :

Fe, Sc, Rb, Br, Te, F, Ca

NTA AbhyasNTA Abhyas 2020Classification of Elements and Periodicity in Properties

Solution:

(i) Alkali and alkaline earth metals are most electro-positive. 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.
