Electronic configuration K L M N

2 8 18 1

Answer 2

Answer:

The atomic number of copper is 29 and its electronic configuration is $1s^{2}2s^{2} 2p^{6}3s^{2}3p^{6}3d^{10}4s^{1}$.

Explanation:

Copper belongs to group 11 and period 4 in the periodic table. Thus it is a d-block element. The atomic number of copper is 29. The electronic distribution per shell is 2, 8, 18, 1. So the electronic configuration of copper can be written as $1s^{2}2s^{2} 2p^{6}3s^{2}3p^{6}3d^{10}4s^{1}$.

Copper is a malleable and ductile metal with high electrical and thermal conductivity.
