1.) Why Francium is the biggest element with the lowest IE and EN?
Francium is the biggest element with the lowest Ionization Energy because it has seven electron shells and only one valence electron. This tells us that it is very reactive in wanting to lose an electron and that since it has seven shells, it has a very weak attraction to its valence electron since it is so far away. The low electronegativity is because it has one valence electron which it wants to lose and not gain valence electrons. That is why its ability to gain an electron is so low.
2.) Why Helium is the smallest element with the highest IE?
Helium is the smallest element with the highest ionization energy because it is so small and there is only one shell, the protons exert such pull to keep the electrons close to the nucleus. So, the energy to remove an electron is the highest in the periodic table based on its size and number of electron shells.
3.) Why Noble Gases don't have EN values?
Noble Gases dont have electronegativity values is because electronegativity is the ability for an atom to gain an electron and Noble Gases already have 8 valence electrons. Noble Gases do not want to gain or lose electrons as it already has a perfect 8. That is why it does not have electronegativity values.
4.) Why Fluorine has the highest EN?
Fluorine has the highest electronegavity because it is a very small atom with only 2 electron shells. It exerts the most pull from its positive nucleus and it has 7 valence electrons so it wants another valence electron to become a noble gas.
