Question

Rank the following elements in order of decreasing metallic character (from most metallic to least metallic):

Sr, Rb, Mg, F, Cl

science chemistry

Answer 1

Answer #1

Rb > Sr > Mg > Cl > F (decreasing order of metallic character)

In a Row (period) from left to right metallic character decreases

In a group from top to bottom metallic character increases.

Rb and Sr belong to same period of elements. In which Rb belongs to Group IA and Sr belongs to Group IIA.

Group IA elements are most metallic, Since they looses its electron easily to form stable nearest nobel gas configuration.
