Question

write electronic configuration of CU + ion​

Answer 1

Answer:

[Ar] 3d¹⁰ 4s¹

Atomic number: 29

Symbol: Cu

Explanation:

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.

NOTE: Copper is an exception to the rules for writing electron configurations!

Answer 2

Answer:

2,8,18,1

is the electronic configuration of CU +
