Why Francium is the biggest element with the lowest IE and EN?
Francium is the biggest element because it has the most shells it has the maximum and because it is so reactive it has a low IE and low EN. It also has fever valence electrons. It has a low ionization energy because it is easy for the atom to lose an electron, and it has a low Electronegativity that means it is hard for it to gain an electron. It has fewest protons ,so its holds electrons the weakiest. has electrons further out.
Why Helium is the smallest element with the highest IE?
first period and first row has one shell. Helium has plus 2 that pulls electrons closer in.
Helium is the smallest element with the highest IE because it is located at the top right corner of the periodic table and it is the first noble gas. As we all now Noble gases don't have an EN but they do have an IE.
Why Noble Gases don't have EN values?
Noble gases have a full shell , they don't try to react to gain an electron.
Why Fluorine has the highest EN?
Of the elements that are non noble gases it is the smallest and the best at attracting electrons and it is one less than the Nobel gas configuration.
