In a graph comparing atomic radius, electronegativity, and ionization energy, the variables can typically be organized as follows:
-
Independent Variable: This is usually the variable that is manipulated or categorized in the study. In many cases, the independent variable is the element or the position on the periodic table. For instance, the elements increase in atomic number as you move from left to right across a period or from top to bottom within a group.
-
Dependent Variable: This is the variable that responds to changes in the independent variable. In this context:
- Atomic Radius: This would be plotted as it changes based on the position of an element in the periodic table.
- Electronegativity: Similarly, this would be measured based on the element's position, generally decreasing down a group and increasing across a period.
- Ionization Energy: This would also depend on the position of the element in the periodic table and would typically increase across a period and decrease down a group.
So, in general terms:
- Independent Variable: Position of the element in the periodic table (e.g., atomic number or group/period).
- Dependent Variables: Atomic radius, electronegativity, and ionization energy, as these values change based on the element's position.
