Why do you remove electrons from the highest energy levels first? Ex: from 5s^2 before 4d^10

Electrons are removed from the highest energy level because they are the furthest from the nucleus.

Just like was said above, you remove the outermost electrons because they are furthest from the nucleus and therefore they have the least amount of pull. Since it's the furthest out, it's the most loosely bound. That would make them the easiest to remove.

You remove from the outermost electrons as they are the furthest away from the nucleus and require less energy to remove.

make sure to switch d and s when writing configurations. But also, it is important to remember that 4s fills up first.
