Scandium (Sc) is the 21st element on the periodic table, so it has 21 electrons in its neutral state. Here's how you would draw its electron configuration:

1. Start with the first energy level. The first energy level can hold up to 2 electrons. So, we put 2 electrons in the 1s orbital. We denote this as 1s².

2. Move to the second energy level. This level can hold up to 8 electrons. There are 2 in the 2s orbital and 6 in the 2p orbital. We denote this as 2s² 2p⁶.

3. Move to the third energy level. This level can also hold up to 8 electrons, but we only have 3 left. So, we put 2 in the 3s orbital and 6 in the 3p orbital. We denote this as 3s² 3p⁶.

4. We still have 9 electrons left. The fourth energy level can hold up to 18 electrons, but we only need to place 9. We put 2 in the 4s orbital and the remaining 7 in the 3d orbital. We denote this as 4s² 3d⁷.

So, the electron configuration for a neutral atom of Scandium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁷.
