1.Why Francium is the biggest element with the lowest IE and EN?
A: Francium has 7 shalls and it's the most shalls over all. But Fransium has the smallest amount of electrons pulling in the inner shell. It doesn't use a lot of energy because it's so far away. Francium is the most reactive metal.
2.Why Helium is the smallest element with the highest IE?
A: Because Helium is the smallest element that has only one shall and 2 electrons are being held togerther. It is smaller than Hydrogen but heavier than Hydrogen.
3. Why Noble Gases don't have EN values?
A: Because Noble Gases have full of eight valence shells, so it won't neither gain or lose elecrton.
4. Why Fluorine has the highest EN?
A: Because Fluorine is the most reactive nonmental which has the smallest atomic radius, largest ionization energy, so it has the highest EN.
