What important subatomic part determines the elements chemical properties?

How did Mendeleev list the elements?
The most important principle was the listing in groups, after similar chemical or physical properties.

they will cmbine
What role of properties of elements and simple molecules play in chemical evolution?
The most important is the electronegativity of chemical elements.
What two properties are the modern periodic table based on?
Properties of elements are periodic function of atomic number. Elements with same chemical properties are grouped together.
What are the two especially important properties that Dmitri mendeleev noted about the elements?
Dmitri Mendeleev noted that elements displayed periodicity in their properties, with similar properties occurring at regular intervals when elements were arranged in order of increasing atomic mass. He also recognized that there were gaps in the sequence of known elements, which led him to predict the properties of undiscovered elements.
