Which of these group 14 elements has the most metallic properties? 1. c 2. ge 3. si 4. sn

The correct answer is option(4).

Explanation:

Metal have property of readily loosing an electron.

When we move down the group , atomic size of the atom increases by which valence electrons move far away from the nucleus. And ability to loose an electron(s) from the valence shell also increases. Hence, metallic character increases on moving down the group.

From the given options of elements of group 14,tin will be last element in the group with the highest metallic character than the carbon , germanium and silicon.

Hence, the correct answer is tin(Sn).
