Losing electrons

Postby Izzie Capra 2E » Mon Oct 28, 2019 8:41 pm

I am still confused why, for Titanium, you would take electrons away from the 4s orbital before the 3d orbital even though 3d2 is the outermost shell...

3d fills up after 4s but 4s would still have higher energy because it is in the fourth energy level. Electrons are removed from the outermost/highest energy levels/shells.

When there are electrons in the 3d block and the 4s block, you typically take away the 4s electrons first. This is because 4s is in a slightly higher energy state than the 3d block. Because the 4s electrons have higher energy, they are the first to go when losing electrons, since they are further from the nucleus. This also contributes to why the electron configuration for Cr is [Ar]3d^5 4s^1 and not [Ar]3d^4 4s^2 and similarly for the Co exception

What happens to when we have more than 1 electron systems?
