Why was Mendeleev's periodic table considered a good model?
Mendeleev's periodic table was considered a good model because it organized elements based on their atomic mass and properties, allowing for predictions of undiscovered elements and their properties.
How many types of atom do you have?
You mean elements? So far scientists have brought out some 109 elements. If you mean atom model, then first Prout's model Then Thomson's, Rutherford's, Bohr's, Sommerfeld's. Finally vector atom model.
Why is Mendeleev's periodic table considered a viable scientific model?
Mendeleev's periodic table is considered a viable scientific model because it successfully organized the elements based on their properties and predicted the existence and properties of yet-to-be-discovered elements. It laid the foundation for the modern periodic table and influenced the development of our understanding of the elements and their relationships.
How can scientist test the correctness of a scientific model?
The scientists test whether the model can be used to make accurate predictions. Scientists in 1750 would have not been able to develop a table like Mendeleev because there was only 17 known elements to work with, the scientists would not have enough data.

What information did scientist study in order to develop the model of the earth?
Scientists study a variety of data, including seismic waves, rock samples, and magnetic properties of rocks, to develop the model of the Earth. By analyzing these data, scientists have been able to understand the Earth's composition, structure, and dynamics.
What is the name of the model developed by scientists to describe the arrangement of molecules within the structure?
The model developed by scientists to describe the arrangement of molecules within a structure is called a molecular model or molecular structure model. These models help visualize the spatial arrangement of atoms and bonds within a molecule, providing valuable insights into its properties and behavior.
Who where the DNA scientists that used model building to determine the structure of DNA.?
The DNA scientists who famously used model building to determine the structure of DNA were James Watson and Francis Crick. In 1953, they constructed a double helix model based on available experimental data, including X-ray diffraction images produced by Rosalind Franklin. Their work was pivotal in elucidating the molecular structure of DNA, which laid the foundation for modern genetics.
Why was the atom model created?
The atom model was created to provide a conceptual framework for understanding the structure and behavior of matter. Early scientists, like John Dalton, proposed the model to explain observations related to chemical reactions and the properties of elements. Subsequent developments by researchers such as J.J. Thomson, Ernest Rutherford, and Niels Bohr refined the model to account for discoveries related to atomic particles and energy levels, ultimately leading to a more comprehensive understanding of atomic structure and behavior in chemistry and physics.
What metallic properties could be explained by the metallic bond model?
Scientists first laid down the basic constitution of a metal. Metals are composed of ions surrounded by electrons. Experimenting on the ion's bonding properties and its attraction to electrons generated the properties of metals.
How did bohr's new model account for the periodic repetition of properties of the elements?
Bohr's model, based on quantized energy levels for electrons in an atom, explained the periodic repetition of elemental properties through the arrangement of electrons in these energy levels or shells. As elements are organized in the periodic table, their chemical behavior is influenced by the number and configuration of their outermost electrons. This arrangement leads to similar chemical properties within groups of elements, as those in the same group have the same number of valence electrons, resulting in comparable reactivity and bonding characteristics. Thus, Bohr's model provided a framework for understanding the trends observed in the periodic table.
What is preprocessing in finite element analysis?
preparation of a 2D or 3D model for analysis of stress concentrations within the small elements. It basically implies assigning material properties, defining boundary and loading conditions in a model
