Introduction to Atomic Properties
Introduction to the periodic properties including atomic radius, electronegativity, electron affinity, and the importance of understanding them for chemistry and the periodic table.
Understanding Atomic Radius
Explanation of atomic radius and its relation to the number of electron layers, comparisons between elements, and the effects of increasing atomic number and number of layers on atomic radius.
Ion Radius
Discussion on ion radius, distinguishing between cations and anions, and how gaining or losing electrons affects ion size.
Ionization Energy
Explanation of ionization energy, the energy required to remove an electron from an atom, and how it relates to atomic size and electron distance from the nucleus.
Electronegativity
Explanation of electronegativity, the ability of an atom to attract electrons in a chemical bond, and its relationship to atomic size and metallicity.
Electron Affinity
Explanation of electron affinity, the energy released when an atom gains an electron, and its relation to electronegativity and stability.
