Mendeleev's characteristics on the periodic table organization
Mendeleev's periodic table was characterized by grouping elements with similar properties together in the same group, arranging elements in order of increasing atomic mass, leaving gaps for undiscovered elements, and predicting the properties of these missing elements.
One of the important aspects of Mendeleev's table was that elements with similar properties were placed in the same vertical columns, called groups. This organization helped in understanding the periodicity of elements and their chemical behavior.
Mendeleev's approach demonstrated that elements in the same column exhibit similar chemical properties due to their comparable electronic configurations.
