How many electron rings dose copper have?

Answer 1

Just square (multiply it by itself) the number of rings, then multiply that answer by 2...

ex. 1) 1st ring 1*1=1 1*2=2 so the 1st ring can hold 2

ex. 2) 3rd ring 3*3=9 9*2=18 so the 3rd ring can hold 18

ex. 3) 8th ring 8*8=64 64*2=128 so the 8th ring can hold 128

etc. etc.

Actually, the first ring can hold up to 2. Then the next up to 8, and the next up to 8, and the ring after that up to 8, and so on. First ring hold up to 2, then all the rest can hold up to 8 electrons.

Answer 2

If by "ring" you mean electron shells then it goes 2-8-8-18-32-64.
Lowest energy level always has 2 electrons (e.g. Hydrogen/Helium)
Then the next highest energy level has 8 electrons for stability.

The rule governing these assignments is the "Octet Rule".

Answer 3

Cu has 1 or 2 electrons in the 4th p-orbital (leaving 18 or 17 in 3d-orbital).

When they are 'lost' in an ionic bond, then cuprous (Cu1+) or cupric (Cu2+) ions are formed.

Answer 4

Electronic configuration of copper: [Ar]3d104s1 (2,8,18,1 electrons per shell)

Answer 5

2, 8, 17, 2
