THE PERIODIC TABLE AND PERIODIC TRENDS

What is Atomic Radius?

Periodic Trend

Explain the Trend

Cations

Anions

Ionic Radius Isoelectric Ions

Ionization Energy Trend

General Trend

Explain the Exceptions

1st, 2nd, 3rd, ... Ionization Energies

Electron Affinity > 0 indicates that the negative ion is higher in energy than the atom and thus less stable.

Explain the Trend

All Together

ELECTRONEGATIVITY An artificial property – created to make comparisons of different elements easier. Electronegativity is the ability of an element to attract an electron to itself.
