@Amber1975 excellent question
To understand this we need to look at the nucleus of an atom.
An atom has an nucleus that's positively charged, because protons have a positive charge while neutrons have no charge. both protons and neutrons are in the nucleus.
So far follow?
think of our atom like this.
Opposite charges attract, right?
well outside the nucleus we have electrons they are negatively charged.
the positive charge of the nucleus is attracted to the negatively charged electrons
Not the answer you are looking for? Search for more explanations.
Now look at this model
now, you can see from this model that the shells, where our electrons are in, some are closer to the nucleus than others
If you notice the closer the electrons are to the nucleus they are going to be held more tightly, because they are closer to the positively charged nucleus.
the valence electrons are the farthest out from the nucleus, so they are far from the positively charged nucleus .
IONIZATION ENERGY the amount of energy it takes to remove an electron from a shell. in a neutral gaseous atom.
If something is farther from the nucleus, it's going to be easier to remove, require less energy, and will have a lower ionization energy than an inner core electron.
