Ionization energy is the amount of energy required to remove an electron from a gaseous atom or ion.
Think of ionization energy like the force needed to pull a magnet off your fridge. The stronger the magnet (or in this case, the more tightly held the electron), the more effort (energy) it takes to remove it.
Electron Affinity: This is the amount of energy released when an electron is added to a neutral atom to form a negative ion.
Valence Electrons: These are electrons that reside in the outermost shell surrounding an atomic nucleus and can participate in chemical reactions.
Atomic Radius: This refers to the size of an atom, typically measured by the distance from its nucleus to its outermost electrons.
