Why Francium is the biggest element with the lowest IE and EN?
- It has the most number of shells. It dosen't take much energy to remove an electron.
Why Helium is the smallest element with the highest IE?
- He has only one shell with two protons in the nucleus that takes alot of energy to remove electrons.
Why Noble Gases don't have EN values?
- Noble gases have a full valence shell and have no tendency to gain electrons.
Why Fluorine has the highest EN
- That means fluorine has only nine electrons flying around in orbitals while iodine has 53 of them.
