Here's why:
* Family 14 elements: Carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn), Lead (Pb), and Flerovium (Fl).
* Metallic character: The trend in family 14 is that metallic character increases down the group.
* Carbon and Silicon are nonmetals.
* Germanium is a metalloid, meaning it has properties of both metals and nonmetals.
* Tin and Lead are metals.
* Flerovium is a synthetic element with a very short half-life and its properties are not fully characterized.
Therefore, only Tin (Sn) and Lead (Pb) are metals in family 14.
