A.) The number of electron shells increases.
Changes in the independent variable lead to changes in the dependent variable during an experiment.
<h3>What is the independent variable?</h3>
The dependent and independent variable
In experiments, two variables are necessary to derive the cause of one factor over the other. These are the independent and dependent variables.
The independent variable can be altered, manipulated and changed in an experimental study.
The effect of such manipulation is observed on another variable which is the dependent variable.
The dependent variable when changes such a change can be recorded to derive the outcome of the experiment.
Hence changes in the independent variable lead to changes in the dependent variable during an experiment.
