Question

Noble gases did not find a place in Newland's Octaves. Explain. [2 MARKS]

Answer 1

Each point: 1 Mark
1. Newland’s classification arranges the elements such that the properties of elements repeat after every eight elements.
2. After the discovery of noble gases, they became the ninth element (and not the eighth), which had similar properties. Hence Law of Octaves became irrelevant.
