Electron configurations:
Ag metal is: [Kr] 4d10, 5s1 ,
so Ag+ ion is in shorthand: [Kr] 4d10, 5s0 or [Kr] 4d10
and in full notaion:
[1s2, 2s2 2p6, 3s2 3p6 3d10, 4s2 4p6] 4d10
Ag, or silver, has the atomic number 47. Its orbital notation is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s1 4d10.
Long-hand version: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^9 Short-hand version: [Kr] 5s^2 4d^9 Note: The "^" symbol means the the following number is in the form of a superscript.
There is one valence electron for silver, so there is one dot
This is not true for all compounds of silver and all forms of silver.
Consider silver fluroide.
Using classical notation: 2.8.8.18.11
And quantum notation: [Kr]5s14d10

Their electron configuration =)
The electron configuration of selenium for a 2- ion is [Kr]4s2.3d10.4p6.
The electron configuration of thaliium III ion is [XE] 4f14 5d10.

Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
The most likely electron configuration for a sodium ion in its ground state is 1s22s22p63s1.
It has 2 electrons in the first shell, and 8 in the second as it gains an electron to form an ion so the configuration is 2,8.
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.
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
The electron configuration of a Copper(II)ion is [Ar]4s0 3d9.
1s2 2s2 2p6 is the electron configuration of the fluoride ion. It has a complete octet and is isoelectronic with neon. Before it becomes an ion, it is 1s2 2s2 2p5 Then it gains an electron and has a negative charge.
