Periodicity and group 2 OCR AS Chemistry

My resources now cover the whole of OCR AS Chemistry.
Each download includes a list of all available lessons and bundles.
This bundle covers all of the OCR A level chemistry specification sections 3.1.1 and 3.1.2.
Resources included are:
• Periodic table past and present
• Periodicity of ionisation energies and melting points
• Group 2

Each topic includes a fully interactive PowerPoint including starter, group activities, questions and plenary along with a worksheet. Answers to all exercises are provided. Some of the resources include a PowerPoint quiz and all are ideal for classroom or home learning.

This bundle is part of a series covering the OCR AS Chemistry specification and relates to the following sections:
Module 3 – The Periodic table and energy
Part 1 –The Periodic Table
3.1.1 Periodicity
3.1.2 Group 2

Please review!

Content covered:
Periodic table past and present
• The history of the periodic table, including Newlands’ and Mendeleev’s contributions
• The structure of the modern periodic table – periods, groups and blocks
• Relationship between electron configuration and the periodic table
• Periodicity – the variation in properties when plotted against atomic number
• Periodicity and metallic character
• Metal and non-metals

Periodicity of ionisation energies and melting points
• First ionisation energy – definition
• Factors affecting ionisation energies: nuclear charge, atomic radius and shielding
• Explanation of shielding
• Successive ionisation energies
• Predicting group from successive ionisation energies
• Periodicity of first ionisation energies
• Trends across a period and down a group
• Explanations of small decreases from group 2 to group 3 and from group 5 to group 6
• Periodicity of structure of elements: giant metallic, giant covalent and simple molecular structures
• Periodicity of melting points and explanation in terms of structure.

Group 2
• Structure and physical properties of group 2 elements
• Electron configuration and formation of ions
• First ionisation enthalpy and reactivity
• Redox reactions of group 2 metals with oxygen, water and acids
• Properties of group 2 compounds
• Group 2 oxides and hydroxides – reactions with acids
• Group 2 oxides – reaction with water
• Solubility and alkalinity of group 2 hydroxides
• Reactions of group 2 carbonates with acid
• Uses of group 2 compounds
