There are 117 known elements at this time, although about 20 or so of these are synthetically prepared, and several of those elements only have a lifetime of fractions of a second before decomposing. And some elements have only had one or two single atoms produced, such as Unonoctium (atomic number 118)!

Carbon, silicon, germanium, tin, lead.
the group 4A elements
Elements in Group 14 on the Periodic Table have similar properties to carbon. These elements are carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). Each of these elements has two electrons in the outermost p orbital, the electron configuration ns2np2, and they tend to adopt oxidation sates of +4 (+2 for the heavier elements due to the inert pair effect). Silicon is most similar to carbon.
they are all in the same group (column) in the Periodic Table
I'm no expert, but both germanium and silicon are located in the same group on the periodic table. Elements in the same group are chemically similar because they contain the same number of valence electrons.
Carbon, silicon, germanium, tin, lead.
germanium, tin, and lead
no
Silicon, Germanium, Tin, Lead belong to carbon family
the group 4A elements
Silicon, which is just below carbon, and Germanium are the two elements that are most like carbon.

Silcon
they are all in the same group (column) in the Periodic Table
there are two elements. those are tin and lead. Tin and lead are NOT metalloids. The two metalloids in group 14 (same group as Carbon) would be silicon (Si) and germanium (Ge).
The semi conducting elements are the metalloid. There is two metalloid in that column: Silicon and Germanium.
