How did scientists first discover what was inside the atom as early as 1900 although powerful microscopes were developed in 1980's?
Rutherford`s Gold foil experiment was probably the most important.
A very elegant experiment his research students Geiger and Marsden measured how much deviation an alpha particle moved from a path.
A beam of alpha particles, generated by the radioactive decay of radium, was directed normally onto a sheet of very thin gold foil. The gold foil was surrounded by a circular sheet of zinc sulfide (ZnS) which was used as an indicator. The ZnS sheet would light up when hit with alpha particles. Under the prevailing plum pudding model, the alpha particles should all have been deflected by, at most, a few degrees. However they observed that a very small percentage of particles were deflected through angles much larger than 90 degrees. From this observation Rutherford was able to observe and deduct the central structure of the atom:[2]

What instrument has played a major role in permitting scientists to discover the chemical makeup of mitochondrion?
Microscopes have played a major role in permitting scientists to discover the chemical makeup of mitochondria. Using electron microscopes, scientists can study the ultrastructure of mitochondria and analyze their membranes and internal components at a molecular level. This has allowed for greater insights into the metabolic processes and functions of mitochondria in cells.
Why did it take so long to discover parts of an atom?
Parts of an atom, such as protons, neutrons, and electrons, are incredibly small and difficult to detect directly. It took a long time to discover these components because early scientists lacked the technology and tools needed to observe them. Through advancements in technology and experimentation, scientists were eventually able to uncover the structure of the atom.
Will scientist discover new elements in the future?
It is possible that scientists may discover new elements in the future through research and experimentation. Discovering new elements would expand our understanding of the periodic table and the properties of matter.
Why do scientists work together?
Scientists work together to share ideas, resources, and expertise to solve complex problems more effectively and efficiently. Collaboration allows scientists to combine their knowledge and skills to push boundaries, discover new insights, and advance science as a collective effort.
Who discover elements argon?
Argon was discovered by two scientists, Sir William Ramsay and Lord Rayleigh, in 1894. They noticed a discrepancy in the density of nitrogen extracted from the air, leading them to discover a new element, which they named argon.
How have microscopes changed the world?
it helped scientists discover small organisms and make the periodic table
How has the microscope allowed scientists to discover new ideas about science?
microscopes have helped scientists to dicover cells and discover their functions. they have helped scientists examine the anatomy of tiny organisms and insects, and inspect organs of all species more closely.

Additionally, microscopes have been crucial in advancing fields like microbiology, cell biology, and materials science.
When did Alexander Fleming discover microscopes?
1595
How important were microscopes in the discovery of microscopic organisms?
microscopes were very important then because we wouldn't even know about microscopic organisms to even discover them

What have microscopes discovered?
Microscopes have helped discover everything that is too small to see with your eyes. Conventional microscopes like the ones you would use in schools to look at cells with helped us to discover.cells. They also help scientists to see smaller components of larger objects. Electron microscopes (extraordinarily expensive) were only invented in 1933, but these allowed us to see MUCH smaller things such as atoms and the individual particles that make up atoms.
