Question

name the element in modern periodic table which has highest and lowest electron affinity,electron negativity and ionsiation energy

Answer 1

Dear student,
Chlorine has the highest electron affinity while mercury has the lowest electron affinity.
Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element, while francium is one of the least electronegative.
The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest
