  • Antoine Lavaisier

    Antoine Lavaisier
    Antoine Lavaisier revolutionized chemistry. Thanks to Priestly’s experiment, he recognized oxygen’s significance and that phlogiston simply didn’t exist. He is known as the father of chemistry. He was the first scientist to define what an element was.
  • elements

    Now 33 elements replaced the ancient 4.
