Question

Give the electron configurations for the elements given. use the noble gas core preceding for the inner electrons.

Answer 1

Noble Gas Cores have following electronic configuration

He  =  1s²
Ne  =  [He] 2s², 2p⁶
Ar  =   [Ne] 3s², 3p⁶
Kr  =   [Ar] 4s², 4p⁶
Xe  =  [Kr] 5s², 5p⁶

Now solving for question elements,

Germanium = Ge  =  [Ar] 3d¹⁰, 4s², 4p²

Nickle = Ni  =  [Ar] 3d¹⁰, 4s²

Tunsten = W  =  [Xe] 4f¹⁴, 5d⁴, 6s²

Titanium = Ti  =  [Ar] 3d², 4s²

Iron = Fe  =  [Ar] 3d⁶, 4s²

Zinc = Zn  =  [Ar] 3d¹⁰, 4s²
