Every element with more protons than ______ is formed from a supernova explosion*1 pointHydrogenHeliumCarbonIron

Step 1: Break Down the Problem

To determine what element has the fewest protons and is formed through processes other than a supernova explosion, we must identify the elements listed and their respective atomic numbers (number of protons) while focusing on their formation processes.

Step 2: Relevant Concepts

1. Hydrogen (H): Atomic number 1
2. Helium (He): Atomic number 2
3. Carbon (C): Atomic number 6
4. Iron (Fe): Atomic number 26

Most elements with atomic numbers greater than 26 are formed in supernova explosions.

Step 3: Analysis and Detail

• Hydrogen and Helium: These are formed primarily during the Big Bang nucleosynthesis, thus they do not require a supernova for their formation.
• Carbon: This element can be formed in the interiors of stars and through nuclear fusion processes.
• Iron: While Iron is formed in stars as they die, heavier elements (>Fe) require the extreme conditions of a supernova explosion to form.

Step 4: Verify and Summarize

Based on the atomic numbers, all elements with more protons than Iron (Fe), which has an atomic number of 26, are formed from supernova explosions.

Final Answer

Every element with more protons than Iron (Fe) is formed from a supernova explosion.
