Ge and Si have a valence shell with 4 electronics making them the starting point for semi-conductors. When mixed with atoms that have 3 or 5 electrons in the valence shell (AKA tri-valent and penta-valent) the blending or doping creates P-type and N-type materials - the building blocks for semi-conductors
Silicon (Si) and Germanium (Ge) are located in the same group (Group 14) of the periodic table, which means they have the same number of valence electrons. As a result, they exhibit similar chemical properties such as forming covalent compounds, sharing electrons, and having the ability to act as semiconductors.
Ga,Ge,Si are few examples for metalloids. They have metal and non metal properties.
Sn, because it is metal
Mg is the most metallic in character among the given atoms. It is an alkali earth metal with two valence electrons, making it more likely to lose electrons and exhibit metallic properties. Silicon (Si) and Germanium (Ge) are metalloids with properties between metals and nonmetals, while Iodine (I) is a nonmetal.
Lead (Pb) is more similar to Silicon (Si) because they are both metalloids, while Germanium (Ge) is also a metalloid but has a slightly different atomic structure than Si and Pb. Lead shares more chemical properties with Silicon, such as forming covalent bonds and having similar physical properties.

For Si it is 0.6or 0.7 and for Ge 0.3 or 0.2.Both values correct for both si and ge

Lead shares more chemical properties with Silicon, such as forming covalent bonds and having similar physical properties.
Ge
Ge has higher conductivity than Si. Because at room temperature the electron and hole mobility for Ge is larger than those of Si. Another explanation is the lower band gap of Ge than Si.
the energy required to break covalent bond in si is 1.1ev and in ge is 0.7ev
for germanium it is 0.3 and for silicon it is 0.7
格雷格(ge lei si )or 格瑞格(ge rui si)
Ge (Germanium) and Si (Silicon) are both from group 14 in the periodic table. They are in the same group but not in the same period. Ge is in period 4, while Si is in period 3.
