Silicon Electron Configuration

Silicon Electron Configuration

Does the ground state provide electron configuration for silicon and copper? ۔

Provides electronic configuration of silicone ground condition.

If necessary, indicate a complete electronics configuration with an exponent. For example, Lee's setting will be entered as 1s 22s 1.

Determine the Copper Ground State Electronics configuration.

If necessary, state the order of the electrons with an exponent. For example, Lee's setting will be entered as 1s 22s 1.

I keep misunderstanding this issue because I always misunderstand, but I don't understand what I'm doing wrong, please help!

If 1s 2 2s 2 2p 6 3s 2 3p 2.

Co (real) 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 1

Partner (expected) 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 9

I will be wary of copper. I registered the original e-setting for an item and a missing item, looking for the expected e-setting.
