First Ionisation Energy: Periodic Table Trends
This video explains how first ionisation energy changes down a group and across a period in the periodic table. Exceptions to the general trend across periods 2 and 3 for group III and group V elements are also shown fully using examples.
This is a short section from the full video lesson first ionisation energy: • First Ionisation Energy
For AQA, OCR (A), Edexcel and CIE A-level and IB Chemistry.
Down a group: 00:46
Across a period: 09:01
Exceptions across a period (group III and group V elements): 11:05
Example - 1st I.E of Aluminium compared to Magnesium: 12:03
Example - 1st I.E of Sulphur compared to Phosphorus: 13:55
