Here’s a breakdown of the composition: ===== - Hydrogen (~74% by mass): The most abundant element. Hydrogen nuclei (protons) are the primary fuel for the nuclear fusion processes that power the Sun. ===== * Helium (~24% by mass): The second most abundant element, created as a product of hydrogen fusion. * Other Elements (~2%): These include heavier elements like oxygen, carbon, nitrogen, neon, magnesium, silicon, and iron, often referred to as "metals" in astrophysics. ===== - The Sun is not made of solid, liquid, or typical gas—it exists in a plasma state, where atoms are ionized. This means that: - Electrons are stripped away from nuclei, leaving a "soup" of free electrons and nuclei (ions). - This ionized state occurs because of the Sun's extremely high temperatures (millions of degrees in the core). ===== ===== - Protons: The nuclei of hydrogen atoms. ===== * Neutrons: Found in the nuclei of helium and heavier elements. * Electrons: Freely moving around, contributing to the plasma. ===== - In the Sun's core, hydrogen nuclei (protons) undergo nuclear fusion, combining to form helium. This process releases immense amounts of energy, which eventually radiates outward as heat and light. ===== In summary, the Sun is indeed made of particles—protons, neutrons, and electrons—all interacting in a plasma state. These particles are the building blocks of the Sun's matter and the source of its energy.
