Question

What is the electronic configuration of
a. Copper
b. Iron
c. Chlorine ​

Answer 1

Answer:

a . Copper

In order to write the Copper electron configuration we first need to know the number of electrons for the Cu atom (there are 29 electrons). Once we have the configuration for Cu, the ions are simple. When we write the configuration we'll put all 29 electrons in orbitals around the nucleus of the Copper atom.

I hope it helps uh....!!

and plzz dont be rude if u don't wanna tell ur intro don't tell but at least plzz talk politely

Answer 2

Explanation:

a.electron configuration for Copper will be 1s22s22p63s23p64s23d9.

c.Chlorine electron configuration will be 1s22s22p63s23p5
