Give the ground-state electron configuration for copper(Cu)using noble-gas shorthand?
Express your answer in condensed form as a series of orbitals. Forexample, [Ar]4s23d8would be entered as [Ar]4s^23d^8.

Please answer all. I'm so confused.

Which electrons are higher in energy, 4s or 3d?

And specifically, which of the following possesses the highestenergy electron?

A) Br-
B) Ca2+
C) Cr+
D) As

Br- --> [Kr] or[Ar]3d104s24p6
Ca2+ --> [Ar] or[Ne]3s23p6
Cr+ --> [Ar]3d5
As --> [Ar]4s23d104p3

Could you tell me please why the correct answer is As with4p3
electrons, despite the fact that Br- has 4p6 electrons?Is it because
Br- has an electron configuration of a noble gas and thus haslower
electron energies in its outermost shell than As? If so, than ifwe
have a noble gas` electron configuration for any ion, can wedisregard
the rule that says that “electron energy level is determined bythe
first two quantum numbers (n and l)” ?
