Teach atomic structure and periodic trends

Predict element properties and periodic trends

Chemistry teaching and predicting bonding behavior from periodic relationships.

• · atomic number or element symbol
• · ionization state (optional)

• · electron configuration
• · periodic trend prediction (size, ionization energy, electronegativity)
• · isotope/radioactivity data

Element symbol or atomic number valid

• · Lanthanide/actinide exceptions to aufbau
• · transition-metal d-block filling anomalies
• · relativistic effects for heavy elements

• · Aufbau, Hund, Pauli principles
• · periodic-law block structure
• · trend prediction rules
