**Fix any errors in these proposed electron configurations.**

| number of electrons in atom | proposed electron configuration                          |

### Analysis of Electron Configurations

- **32 Electrons:**
  - Correct configuration should be: 
    - 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰, totaling 32 electrons.
  - Errors: 
    - "1p" and "2d" do not exist in valid configurations.
    - The sequence and count are incorrect.

- **20 Electrons:**
  - Correct configuration should be:
    - 1s² 2s² 2p⁶ 3s² 3p⁶ 4s², totaling 20 electrons.
  - Errors:
    - "3d" fills after 4s, but it's unnecessary here.
    - Incorrectly extends to d orbitals.

- **12 Electrons:**
  - Correct configuration should be:
    - 1s² 2s² 2p⁶ 3s², totaling 12 electrons.
  - Errors:
    - "2p⁸" is not possible; 2p can only hold up to 6 electrons.
