Edexcel IAL Chemistry AS 2.17 Periodic ionisation-energy data

Pearson Edexcel IAL Chemistry syllabusChemistry YCH11First assessment 2019
Label axes and units, select a linear scale that uses the grid, plot each point accurately and convert a logarithmic reading back to the requested energy value.
How this is tested
- Plot ionisation-energy data with labelled axes, units, scale and accurate points.
- Use a log-ionisation graph to estimate and convert a missing energy value.
- Identify periodic behaviour from repeating patterns in ionisation-energy data.
