We can represent the proton and electron with simple colored circles for the simulation. The proton will be red, and the electron will be yellow. Let's start by setting up the basic structure for this simulation.\n\nWe'll create classes for the proton and electron, and add some basic physics to simulate attraction between them. Here's how you can set it up:\n\n```javascript\n// script.js\nlet proton;\nlet electron;\n\nfunction setup() {\n createCanvas(windowWidth, windowHeight);\n proton = new Proton(width / 2, height / 2);\n electron = new Electron(random(width), random(height));\n}\n\nfunction draw() {\n background(255);\n\n proton.display();\n electron.display();\n\n electron.attract(proton);\n}\n\nclass Proton {\n constructor(x, y) {\n this.position = createVector(x, y);\n this.color = 'red';\n }\n\n display() {\n fill(this.color);\n noStroke();\n ellipse(this.position.x, this.position.y, 20, 20);\n }\n}\n\nclass Electron {\n constructor(x, y) {\n this.position = createVector(x, y);\n this.color = 'yellow';\n this.velocity = createVector();\n }\n\n display() {\n fill(this.color);\n noStroke();\n ellipse(this.position.x, this.position.y, 10, 10);\n }\n\n attract(proton) {\n let force = p5.Vector.sub(proton.position, this.position);\n force.setMag(0.05); // Adjust this value to change the strength of attraction\n this.velocity.add(force);\n this.position.add(this.velocity);\n }\n}\n```\n\n### Explanation:\n- **Proton and Electron Classes**: These classes represent the proton and electron with positions and colors.\n- **Display Function**: Each particle is drawn as a circle on the canvas.\n- **Attraction**: The electron is attracted to the proton.

When they collide, we can visually indicate it by changing their colors temporarily.\n\nHere’s how to implement these changes:\n\n```javascript\n// script.js\nclass Proton {\n constructor(x, y) {\n this.position = createVector(x, y);\n this.color = 'red';\n this.size = 20; // Set a size for the proton\n }\n\n display() {\n fill(this.color);\n noStroke();\n ellipse(this.position.x, this.position.y, this.size, this.size);\n }\n\n checkCollision(electron) {\n let d = dist(this.position.x, this.position.y, electron.position.x, electron.position.y);\n if (d < this.size / 2 + electron.size / 2) {\n this.color = 'purple'; // Change color on collision\n electron.color = 'purple'; // Change color on collision\n } else {\n this.color = 'red'; // Reset color\n electron.color = 'yellow'; // Reset color\n }\n }\n}\n\nclass Electron {\n constructor(x, y) {\n this.position = createVector(x, y);\n this.color = 'yellow';\n this.size = 20; // Set a size for the electron, same as proton\n this.velocity = createVector();\n }\n\n display() {\n fill(this.color);\n noStroke();\n ellipse(this.position.x, this.position.y, this.size, this.size);\n }\n\n attract(proton) {\n let force = p5.Vector.sub(proton.position, this.position);\n force.setMag(0.05); // Adjust this value to change the strength of attraction\n this.velocity.add(force);\n this.position.add(this.velocity);\n }\n}\n```\n\n### Explanation:\n- **Size Property**: Both the `Proton` and `Electron` classes now have a `size` property set to 20, making them the same size.\n- **Collision Detection**: The `checkCollision` method in the `Proton` class checks the distance between the two particles. If they collide, their colors change to purple. If not, they revert to their original colors.\n- **Using the Collision Check**: You'll need to call the `checkCollision` method in the `draw()` function.\n\nHere's how to include the collision check in your `draw()` function:\n\n```javascript\nfunction draw() {\n background(255);\n\n proton.display();\n electron.display();\n\n electron.attract(proton);\n proton.checkCollision(electron); // Check for collision\n}\n```\n\nGo ahead and update your `script.js` file with these changes!
