Law of octaves stateda)Every eighth element had properties similar to ...
Newland's Law of octaves stated that if elements (known at Newland's time) were arranged in increasing order of their atomic weights, every eighth element had properties similar to the first element. For example, Li and Na have similar properties.

Law of octaves stateda)Every eighth element had properties similar to ...
The law of octaves is a concept proposed by John Newlands, an English chemist, in 1864. It was one of the earliest attempts to organize the elements based on their chemical properties. According to this law, when the elements are arranged in order of increasing atomic mass, the properties of every eighth element are similar to the first element.
Explanation:
1. Law of Octaves: The law of octaves states that the properties of elements are repeated after regular intervals of eight elements.
2. Arrangement of Elements: Newlands arranged the known elements in order of increasing atomic mass. He observed that when the elements were arranged in this manner, there was a periodic repetition of properties.
3. Similarity of Properties: Newlands found that every eighth element had properties that were similar to the first element. This means that the elements at the first and ninth position, second and tenth position, third and eleventh position, and so on, shared similar properties.
4. Example: For example, Newlands noticed that lithium (Li) and sodium (Na) had similar properties, so did beryllium (Be) and magnesium (Mg), boron (B) and aluminum (Al), and so on.
5. Limitations: Although the law of octaves showed periodicity in the properties of elements, it had limitations. It failed to accommodate all the known elements at that time, and it did not explain the underlying reason for the repetition of properties.
6. Recognition and Acceptance: The law of octaves was initially met with skepticism and criticism. However, it laid the foundation for the development of the modern periodic table.
7. Advancement: Dmitri Mendeleev, a Russian chemist, later expanded on Newlands' work and proposed the periodic law, which states that the properties of elements are periodic functions of their atomic numbers.
8. Modern Periodic Table: The modern periodic table is based on the periodic law and arranges the elements in order of increasing atomic number. It organizes the elements into groups and periods based on their similar properties and electronic configurations.
In conclusion, the correct answer is option 'A' - every eighth element has properties similar to the first element. This observation, known as the law of octaves, was proposed by John Newlands and served as a precursor to the development of the modern periodic table.
