Law of octaves, in chemistry, the generalization made by the English chemist J.A.R New lands in 1865 that, if the chemical elements are arranged according to increasing atomic weight, those with similar physical and chemical properties occur after each interval of seven elements. The image shows the notes of music correlated with the elements.1. What did New lands compared?a. the similarity between the elements to the triads of music, where every third note is comparable to the first.b. the similarity between the elements to the octaves of music, where every eighth note is comparable to the first.c. the similarity between the elements to the triad of music, where every eighth note is comparable to the first.d. None2. How many elements did New lands arranged in an ascending order based on their atomic masses?a. 62b. 63c. 64d. 653. Which elements could not be accommodated into octaves?a. Elements with greater atomic volumesb. Elements with greater atomic massesc. Elements with greater atomic densitiesd. All the options4. Why this method of classifying elements did not leave any room for the discovery of new elements?a. Because elements that were discovered later could not be ’t into the triad pattern.b. Because elements that were discovered later could not be ’t into the octave pattern.5. Give an example where elements of dissimilar properties were grouped together.a. Halogens with cobaltb. Halogens with nickelc. Halogens with platinumd. All the options
