Question

what is the correct abbreviated electron configuration for germanium (ge)?
a) ar4s²3d⁸4p³
b) ar4s¹3d¹⁰4p²
c) ar4s²3d⁵4p⁶
d) ar3d¹⁰4p²
e) ar4s²3d¹⁰4p²

Explanation:

Germanium has an atomic number of 32. The nearest noble - gas with a lower atomic number is argon (Ar, atomic number 18). After [Ar], the electron filling order is 4s, 3d, and 4p. The 4s sub - shell fills first with 2 electrons, then the 3d sub - shell fills with 10 electrons, and finally the 4p sub - shell has 2 electrons for germanium. So the abbreviated electron configuration is [Ar]4s²3d¹⁰4p².

Answer:

e) [Ar]4s²3d¹⁰4p²
