Bohr Models for atoms and ions Quiz tomorrow! 15 marks (2.1-2.10: classifying matter, phase change, atoms, ions, isotopes, Bohr models )

Atoms & Ions – Ions have a charge as a result of gaining or losing electrons. Isotopes – Atoms of an element with differing numbers of neutrons, therefore different atomic masses. Assignment: Workbook 2.7-2.9

Phase Changes – Phase change graph for pure substances Temperature changes (add heat) causes a change in state, pressure affects what temperature is required to reach boiling point/melting point Triple Point – Temp & pressure “sweet spot” where a substance … Continue reading →

Phase Change Graph Temperature: Average kinetic energy of a substance (measured in degrees C)Heat: Total energy (potential and kinetic) of a substance   Assignment: Workbook pg 2.5-2.6
