Question
Within the first three minutes of the universe, which elements were formed?
- 1 point
- Hydrogen
- Helium
- Lithium
- Carbon
- Just protons
- None of the above
Solution
Within the first three minutes of the universe, the elements that were formed include Hydrogen, Helium, and Lithium.
Here's the step-by-step reasoning:
- Big Bang Nucleosynthesis: This process occurred within the first few minutes of the universe's existence.
- Formation of Protons and Neutrons: Initially, the universe was extremely hot and dense, allowing protons and neutrons to form.
- Fusion Reactions: As the universe expanded and cooled, these protons and neutrons underwent fusion reactions.
- Hydrogen: The simplest and most abundant element formed was Hydrogen, consisting of one proton.
- Helium: Through further fusion, some of the Hydrogen nuclei combined to form Helium.
- Lithium: In smaller quantities, some Helium nuclei combined with Hydrogen to form Lithium.
Therefore, the correct elements formed within the first three minutes of the universe are Hydrogen, Helium, and Lithium.
