Here's how you can create a timeline with illustrations and text to show how elements form with the concept of atomic number: ### **Timeline Title: The Formation of Elements Across the Universe** 1. **Big Bang Nucleosynthesis (0-3 minutes after the Big Bang)** - **Illustration:** A bright, hot explosion with tiny particles zooming out. - **Text:** - **Era:** Big Bang - **Elements Formed:** Hydrogen (H, Atomic Number 1) and Helium (He, Atomic Number 2), along with trace amounts of Lithium (Li, Atomic Number 3). - **Description:** In the first few minutes after the Big Bang, the universe was extremely hot and dense. Protons and neutrons collided to form the simplest elements. Hydrogen and helium became the building blocks for all other elements. 2. **Stellar Nucleosynthesis (Millions to Billions of Years)** - **Illustration:** A star in the main sequence, with hydrogen atoms fusing into helium. - **Text:** - **Era:** Life of a Star (Main Sequence) - **Elements Formed:** Helium (He, Atomic Number 2), Carbon (C, Atomic Number 6), Oxygen (O, Atomic Number 8) - **Description:** Stars fuse hydrogen into helium in their cores. Over time, in more massive stars, helium atoms fuse to create heavier elements like carbon and oxygen. The atomic number increases as protons are added to the nucleus. 3. **Red Giant Phase (After Hydrogen Burning)** - **Illustration:** A large red star expanding, with layers showing different fusion processes. - **Text:** - **Era:** Red Giant Phase - **Elements Formed:** Neon (Ne, Atomic Number 10), Magnesium (Mg, Atomic Number 12), Silicon (Si, Atomic Number 14) - **Description:** When a star exhausts its hydrogen, it expands and becomes a red giant. In its core, helium fuses into heavier elements like neon, magnesium, and silicon, further increasing the atomic number. 4. **Supernova Nucleosynthesis (End of Massive Stars)** - **Illustration:** A star exploding in a supernova, sca
