The law of octaves was established by British chemist John Newlands in 1865. He observed that when elements were arranged by increasing Atomic Mass, every eighth element exhibited similar properties, analogous to the musical octaves. Newlands' work was a precursor to the development of the Periodic Table, even though it initially received criticism for its limitations.

Which scientist proposed the law of octaves?
The scientist who proposed the law of octaves was John Newlands in 1864. He noticed that when the elements were ordered by atomic weight, every eighth element had similar properties, similar to the musical concept of octaves.
What scientist first established that the universe is expanding?
Edwin Hubble
How do you think the discovery of neon and argon affected the law of octaves?
The discovery of neon and argon provided crucial evidence that challenged the law of octaves, which suggested that elements could be arranged in a sequence based on their atomic weights, with similar properties repeating every eight elements. Noble gases like neon and argon, which did not fit into the established groups of elements, highlighted the limitations of this law and indicated the need for a more comprehensive understanding of periodicity. This ultimately contributed to the development of the modern periodic table, which organizes elements based on atomic number and incorporates the noble gases as a distinct group.
What scientist characterized the the law of octave?
John Newton
Who was the scientist that discovered these distant galaxies?
The scientist who discovered distant galaxies is Edwin Hubble. In the 1920s, Hubble observed that galaxies were moving away from us, leading to the formulation of Hubble's Law, which describes the expansion of the universe. His work fundamentally changed our understanding of the cosmos and established galaxies as separate entities beyond the Milky Way.
Which scientist proposed the law of octaves?

Who is the scientist who established the law of conservation of mass?
Antoine Lavoisier
What is Newland's law of Octave?
what is newlands law of octaves
What scientist established the law of conservation of matter?
The law of Conservation of Mass was invented by a French chemist Antoine-Laurent Lavoisier.
Who developed the law of octaves?
Law of octaves was established by newland, before mandelleve. It states that : The properties of elements will repeat themselves after every 8th element. The series in which the elements were set was determined by newland. The law was not very successful because elements does not follow the same characteristics after mass no 40.
Who is the sccientist who tried to group the elements into octaves?
The scientist who attempted to group elements into octaves is John Newlands. In 1865, he proposed the Law of Octaves, which suggested that elements displayed similar chemical properties at intervals of eight when arranged by increasing atomic mass. This early classification system laid the groundwork for the development of the periodic table, although it was later refined by other scientists like Dmitri Mendeleev.
Who was the scientist who observed a pattern of properties that repeated every eight elements?
The scientist who observed the pattern of properties that repeated every eight elements was John Newlands. He created the Law of Octaves, which grouped elements based on similar properties and noted the repetition every eighth element.
Who started the law of octaves?
by the English chemist J.A.R. Newlands in 1865
What scientist established the structure of DNA?
The scientist who established the structure of DNA was James Watson and Francis Crick.
Who arranged elements using the law of octaves?
John Newlands (England) in 1865.
Who established the law of multiple porportions?
Dalton established the Law of Multiple Porportions.
What scientist defined the universal law of gravitation?
There is no such law for universal gravitation. In Sir Isaac Newton', treatise, the 'Principia'. it is the 'Universal Law of Dynamics'. This law has three parts ;- A body will remain stationery or in uniform motion, unless acted upon by a force. Force is directly proportional to both 'mass' and ' acceleration'. To every force there is an equal and opposite force. Newton based his work on that of two earlier scientists; viz;- #1 Galilieo , who established the Law of of Gravity on EARTH. #2 Johannes Kepler; who established the Law of Planetary motion. Newton 'stood omn the shoulders of giants'.
