Scientists such as Niels Bohr and Ernest Rutherford used atomic spectra to develop models of the atom. They were able to study the unique wavelengths of light emitted by atoms and used this information to propose new atomic models that helped explain atomic structure and behavior.
Example of scientists: Dalton, Thomson. Rutherford, Bohr etc.
Scientists use different types of models to represent compounds because each type of model provides unique insights into the structure and properties of the compound. For example, ball-and-stick models provide a visual representation of atom arrangements, while computational models offer detailed quantitative data on molecular interactions. Using a variety of models helps scientists better understand and predict the behavior of compounds in different contexts.
because they are to small for anyone to study.
That is correct.
Models stepping in when theories are too complex to handle. Theories may be too complicated to handle. In such a case a simplified model may be employed that allows for a solution
Scientists use models of atoms to help them visualize and understand the structure and behavior of atoms. Models provide a simplified representation of complex processes, making it easier to study and predict atomic interactions and properties. This helps scientists develop theories and make predictions about the behavior of matter at the atomic level.
Main reason is that the real atom is already unknown. There was many models, like for example: Dalton Model - the atom was a solid ball. Rutherford - orbital model There are also other people that developed study and created their atomic models like Thomson, Bhor and Somerfield. We have today what scientists call the Nowadays Atomic Model, that is the most advanced model, able to best aproximate of a real atom and explain great number of theories. These models are theories about how is the atom, and a model is overtaken by other, when it is able to explain better the atom behaviour. For example, the model of Rutherford overtaken the model of Dalton. So, they use models to better approximate of a real atom in order to study it, because a real atom is not already known also because it is very hard to study a real atom, because it is very small.
Scientists have split the atom.
they could discover a new atom and it would change
Models of atom are not perfect since they exhibit more features which are not present in model.Hence, an improvement is always required.
Scientists know about the structure of an atom through experimentation, such as using techniques like X-ray crystallography and spectroscopy to study the behavior of atoms. Theories like quantum mechanics also provide a framework for understanding the atom's structure based on experimental evidence.
