Assignment # 25- more Periodic Trends

This assignment explores key periodic trends in regular chemistry, focusing on ionization energy, electron affinity, and electronegativity. It details the first, second, and third ionization energies of sodium, illustrating how they reflect an atom's ability to hold onto electrons. The relationship between ionization energy, atomic radius, ionic radius, electron affinity, and electronegativity is discussed, delving into the implications for covalent bond polarity. Understanding these concepts is crucial for grasping the behavior of elements in chemical reactions.
