Question

electronic configuration of cu​

Answer 1

Answer:

ELECTRONIC CONFIGURATION:

[Ar] 3d¹⁰ 4s¹

Atomic number: 29

Symbol: Cu

Answer 2

Answer:

Explanation:

Correct Electron Configuration for Copper (Cu)

Half-filled and fully filled subshell have got extra stability. Therefore, one of the 4s2 electrons jumps to the 3d9. This give us the (correct) configuration of:

1s2 2s2 2p6 3s2 3p6 3d10 4s1

For the Cu+ ion we remove one electron from 4s1 leaving us with: 1s2 2s2 2p6 3s2 3p6 3d10

For the Cu2+ ion we remove a total of two electrons (one from the 4s1 and one form the 3d10) leaving us with

1s2 2s2 2p6 3s2 3p6 3d9

The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.
