An Atom

An Atom which called Chlorine have 17 electrons..
If we are going to take off an electron from this atom..
It’s quite difficult..
Because of its strong effective nucleus charge..
We need to add on a lot of energy to supply the energy that we need..
If we successfully take off an electron from it,
What is this electron going to be?

It may attract by other atom
Such as Magnesium..
But is the Magnesium willing to accept it?
Its is electron affinity so high…
It is absolutely impossible to occur spontaneously

But..
It successfully occurred..
The electron is finally leave it..
It may get what it want..
But it may lose what it should have..
Its energy..
Its own positions..
And so on..
