The electron configuration of a Copper(II)ion is [Ar]4s0 3d9.

The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
[He] 2s2 3p5 is the electronic configuration of a neutral Fluorine atom.It's -1 ion (F-, fluoride ion), however is: [He] 2s2 3p6, or [Ne]
Positive 1 charge
bromine has 17 electrons in the valence shell. by gaining one electron it gets the electronic configuration of the next noble gas. hence it gains one electron and forms -1 ion

1 valence electron. The electronic configuration of copper is 2, 8, 18, 1
Rubidium (Rb) has a +1 ion, will have the same electron configuration as krypton (Kr) because the +1 status means it has lost an electron. The configuration is written 1s22s22p63s23p64s23d104p6.
Positive 1 charge
in the same way as sodium/potassium forms an ion. Lithium has an electron configuration of 2,1 Sodium has an electron configuration of 2,8,1, Potassium has an electron configuration of 2,8,8,1 Rubidium has an electron configuration of 2,8,8,18,1 Caesium has the electron configuration of 2,8,8,18,18,1 Notice in all cases the last number is '1'. This represents the outer most electron, shell with one electron. Since it is the outer most electron and is shielded by energy shells of electrons from the nucleus, this outer most electron is not strongly held to the atom. The atom readily releases this outermost electron , and the process is called ionisation. Chemically it is represented by the formula M(g) = M^+(g) + e^- NB 'M' is an ATOM 'M^+' is an ION (Not an atom).
A bromine ion has a -1 charge. That's because it is a halogen, and it is an electron "borrower" which wants to steal an electron to "complete" its outer electron shell. When it snags an electron to fulfill that tendancy of atoms to attain inert gas electron configuration, it ends up with that "extra" electron and a -1 charge. This is typical of all halogens, those elements that make up the Group 17 elements.

Fluorine has the electron configuration: 1s22s22p5, sometimes written as [He]2s22p5
