When a copper atom loses an electron to become a cu+
ion, what are the possible quantum numbers of the electron that was lost

1) Find the electron configuration of copper atoms:

Cu: [Ar]3d10 4 s1

2) Focus on valence electrons: those are outermost electrons and, therefor, the first to lose an atom to form an ion.

In this case the only valence electron is 4s1.

The feasible quantun numbers for that electron are.

n (principal quantum number or energy level) = 4
l (Azimuthal quantum number)= 0 (this is because the orbital s can only have this number)
ms (magnetic quantum number) = 0 (this can only be from - l to + l, the in can only be 0(
s (spin quantum number) = +1/2 or - 1/2

(4,0,0, +1/2) or (4,0,0, -1/2)

This is what i found on google “when one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and atp is converted to adenosine diphosphate (adp). likewise, energy is also released when a phosphate is removed from adp to form adenosine monophosphate (amp).” i hope this you .
