From top to bottom in the group the electro positivity increases so that the metallic character increases .
The most reactive metal is francium.
K has more metallic character

metallic character increases
Across a period, the metallic character decreases.
The element in Period 3 that has the greatest metallic character is magnesium. In periods, the metallic character decreases when atomic number increases.

All the four elements listed in the question are non-metals and not metals. So it is not possible to tell the metallic character.
metallic character encompasses all the charateristics of metals, such as the melting point, conductivity, electromagnet properties, density etc. electropositivity is a measure of an element's ability to donate electrons, and therefore form positive ions. In general, the gretaer the metallic character of a metal, the more electropositive it is.
The metallic character decrease from left to right.
From top to bottom in the group the electro positivity increases so that the metallic character increases .
Metallic character increases as one transitions down and right through the periodic table. By definition, francium (Fr) would be the most metallic, but only extremely small amounts of it exist at any given time, thereby rendering caesium (Cs) as the most metallic element.
