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.
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
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.
When are scientific ideas modified-?
Scientific ideas are modified when evidence is found that does not fit the predictions. The scientists determine why and revise the model to fit the new data.
What model do scientists use today to describe how electrons move around the nucleus?
Scientists use the quantum mechanical model to describe how electrons move around the nucleus. This model takes into account both the wave-like and particle-like properties of electrons, providing a more accurate description of their behavior within an atom. It uses mathematical equations based on the principles of quantum mechanics to determine the probability of finding an electron at a given location around the nucleus.
Does the periodic table explain the shell model or does the shell model explain the periodic table?
The shell model explains the organization of the periodic table. The elements in the first period have electrons in the first shell; the elements in the second period have electrons in the first two shells; the elements in the third period have electrons in the first three shells; and so on.
