Transcribed Image Text:**Fix any errors in these proposed electron configurations.**
| number of electrons in atom | proposed electron configuration |
|-----------------------------|--------------------------------------------------------|
| 32 | 1s² 1p⁶ 2s² 2p⁶ 2d¹⁰ 3s² 3p⁴ |
| 20 | 1s² 2s² 2p⁶ 3s² 3p⁶ 3d² |
| 12 | 1s² 2s² 2p⁸ |
### 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.
