How do you find the number of valence electrons in an element?
On your periodic table, Because like a good student I wrote them down when the teacher asked!
Elements of Group 18
The Noble Gases
An atom with a charge.
Ion
Define ionization energy.
The energy required to remove an electron from an atom.
which atom will have the highest ionization energy and why?
Ne, Be, or Li
Ne, it has a full outer shell
