Answer 2

Answer:

FOR CLASS 10 - 2,8,18,1

DON'T USE IT IN 11

Explanation:

As the atomic no. of copper is 29 so it's E.C. should be 1S2 2S2 2P6 3S2 3P6 4S2 3D9

But 3D9 is not stable configuration bcoz if subshells are near half-fill or full-fill configuration then they are either halfly or fully filled bcoz of which configuration of Cu will be 1S2 2S2 2P6 3S2 3P6 4S1 3D10

IN CLASS 10 U CAN WRITE IT AS

2,8,18,1
