Which is the pentavalent impurity is boron or germanium or indium or antimony
Group 14 elements such as silicon or germanium generally act as semi-conductors. Boron, a group 13 element, normally acts as a dopant in semiconductors.
The most common isotope of Germanium has 40 neutrons.
Metalloid, or semi metal is a term used in chemistry when classifying the chemical elements. On the basis of their general physical and chemical properties, nearly every element in the periodic table can be termed either a metal or a nonmetal. However, a few elements with intermediate properties are referred to as metalloids. They are sometimes called (and confused with) semiconductors and semimetals.The following elements are generally considered metalloids:Boron (B)Silicon (Si)Germanium (Ge)Arsenic (As)Antimony (Sb)Tellurium (Te)Polonium (Po)Astatine (At)Inclusion of polonium is somewhat academic because all its isotopes are radioactive.
BORON 511 atomic#=5, atomic mass = 11 (for most common isotope)
