Answer 1

Answer:

E4>E3>E2>E1

As the first electron is removed the atom becomes positively charged. Removal of an electron from positively charged atom requires more energy. So in subsequent removals the energy required will be more.

Answer 2

Answer:

Actually my phone's battery was fully discharged,so here is the other half of the answer.

If we remove atoms one by one the shells will get attracted to the nucleus and thus due to decrease in the distance between the nucleus and shell, it will be more difficult to remove the electrons which are left. That means, the atom will be positively charged after removal of electrons.. And eventually the last electron, the 4th one will come closest to nucleus and will require most energy.

Were you thinking that my answer was completed... Lol.. You even marked that brainliest, BTW, that was a satisfactory answer for a chemistry lover..

I was just asking you whether you know ascending or descending order and that moment my battery discharged... Lol

I answered half here bcz, the editing of answer can only be done for 1 hrs and that answer was not editable.
