3D - 2

The configuration 3d^44s^2 is more stable than the configuration 3d^54s^1?

Is this always true, sometimes true, or never true. Thanks

1. yes because the S orbital is full.
2. An element with this configuration ...3d^54s^1 wants to "lose" the electron in it's 4th shell so that its 3rd shell, which is much more stable, will be its outer shell.
