What is the difference between Germanium and silicon?

Silicon	Germanium
Silicon is the chemical element present in periodic table with atomic number 14 and represented as $\left(\mathrm{Si}\right)$	Germanium is the chemical element present in the periodic table with atomic number 32 and represented as$\left(\mathrm{Ge}\right)$
The chemical electronic configuration is written as follows: $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^2$	The chemical electronic configuration is written as follows: $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{6}3{\mathrm{d}}^{10}4{\mathrm{s}}^{2}4{\mathrm{p}}^2$
No d-orbital electrons are present in it.	d-orbital electrons are present in it.
The atomic radium is smaller compared with Germanium because of smaller atomic number	The atomic radius is larger compared with Silicon.
Silicons are less conductive than Germanium	Germanium is more conductive in nature.
Silicons are used as semiconductors as they can withstand up to higher temperature ranges.	Germanium can not be used as semiconductors as they have a certain limit to temperatures.
