|
|
|
Li, K, Na, Rb
|
|
|
Either A or B
|
|
|
None of the above

Explanation:
Detailed explanation-1: -Reason for being more electropositive:-According to the question Sodium(Na) is more electropositive than Lithium(Li). This is because as we go down the group the number of shells increases, as a result, the distance between the valence electron present in the outermost shell and the nucleus increases.
Detailed explanation-2: -The list of top 5 electropositive elements: Cesium ( Cs ), Rubidium ( Rb ), Potassium ( K ), Sodium ( Na ), Lithium ( Li ) .
Detailed explanation-3: -The correct decreasing order of electropositive character among the following elements is : Fe, Rb, Br, Te, F, Ca. Q.
