Basic terms and trends for the period table
Atomic radius
Radius of an atom
Nuclear charge
Strength of the pull of the positive nucleus
Effective nuclear charge
Strength of the pull of the positive nucleus on its own electrons.
Electron shielding
Full electron shells shield the nucleus’ positive charge from valence shell electrons. It reduces the pull of the nucleus that the valence electrons feel.
Ionisation energy
Amount of energy required to remove an electron
First ionisation energy
How much energy is required to remove a single valence electron.
Electron affinity
Energy change that occurs when electrons are added to elements.
Electronegativity
Nucleus’s pull on the electrons in a chemical bond.
