Boron arsenic germanium gallium odd man out
WebJan 8, 2024 · The atomic radius i.e., the metallic radius of gallium ($135~\mathrm{pm}$) is less than that of aluminium ($143~\mathrm{pm}$). My book provides the following reason: It is due to the presence of additional 10 d-electrons in gallium which offer poor screening effect for the outer electrons from the increased nuclear charge. WebJul 5, 2024 · Jul 5, 2024. 3: Ideal Diode Equation. II. P-N Junction. p-n junction diodes are made up of two adjacent pieces of p-type and n-type semiconducting materials. p-type and n-type materials are simply semiconductors, such as silicon (Si) or germanium (Ge), with atomic impurities; the type of impurity present determines the type of the semiconductor.
