What is the mass number of an atom of GE with 40 neutrons?
Explanation: The atomic no. Z for Ga=31 ; given the Ga symbol, Z has been specified. This isotope contains 40 neutrons in its nucleus; thus we write the isotope as 71Ga .
What is the orbital notation for GE?
The electron configuration of Germanium is [Ar]4s2, 3d10, 4p2.
What is the total number of p orbitals containing?
The total number of p orbitals containing one or more electrons in germanium. 8, every two atoms is an orbital, but each atom has to have an electron in it first before they can double up. The orbitals with the lowest energy are filled first.
How many valence electrons are there in GE germanium and Te tellurium )?
Group 16 of the periodic table is also called the oxygen group. The first three elements—oxygen (O), sulfur (S), and selenium (Se)—are nonmetals. They are followed by tellurium (Te) (Figure below), a metalloid, and polonium (Po), a metal. All group 16 elements have six valence electrons and are very reactive.
