I am currently writing a program to let the user build an atom in javafx, and i decided to show the user the valence electrons in an atom. I also thought it would be nice to make them spin, but I am running into some issues.

This is what I tried:

boolean protonsAreUnder1 = false;
            if(numberOfProtons < 1){
                protonsAreUnder1 = true; 
            }
            
        if (!protonsAreUnder1){   
        //checks if # of protons > 0, or throws exception
            int atomicNumber = numberOfProtons + numberOfNeutrons;

            String[] elementInfo = getElementInfo(numberOfProtons);
            String symbol = elementInfo[0];
            String name = elementInfo[1];
            String valenceElectronsString = elementInfo[2];
            int valenceElectrons  = Integer.parseInt(valenceElectronsString);

            String atomicMassString = Integer.toString(atomicNumber);
            symbolNumberLabel.setText(name + "(" + symbol + ") - " + atomicMassString);

            //max radius for atom, based on the number of nucleons
            double maxRadius = Math.sqrt(atomicNumber) * 2.5;

            double valenceShellRadius = maxRadius + 20;  

            Circle valenceCircle = new Circle(150, 150, valenceShellRadius, Color.TRANSPARENT);
            valenceCircle.setStroke(Color.BLACK );
            valenceCircle.setStrokeWidth(2);
            pane.getChildren().add(valenceCircle);

            double angleBetweenElectrons = 2 * Math.PI / valenceElectrons;

            for(int v = 0; v < valenceElectrons; v++){
                double angle = v * angleBetweenElectrons;
                double x = 150 + valenceShellRadius * Math.cos(angle);
                double y = 150 + valenceShellRadius * Math.sin(angle);

                Circle electron = new Circle(x, y, 3, Color.YELLOW);
                electron.setStroke(Color.BLACK);
                electron.setStrokeWidth(1);
                pane.getChildren().add(electron);
                
               //this is where i was thinking of putting the orbit code
               //but i think this only rotates the electron by itself, and not around the atom
               RotateTransition rotateTransition = new RotateTransition(Duration.seconds(1), electron);
               rotateTransition.setByAngle(360); // Rotate 360 degrees
               rotateTransition.setCycleCount(Animation.INDEFINITE);
               rotateTransition.setInterpolator(Interpolator.LINEAR);
               rotateTransition.play();
            }

But when I run it, the electrons are not moving. I think they are just spinning around themselves.
