Question

nucleosynthesis in stars (due midnight 10/27)

• elements created during the big bang: hydrogen and a little helium were formed in the first few minutes after the big bang. this process is called \big bang nucleosynthesis\.
• elements created through nucleosynthesis in stars: on the periodic table, the elements helium all the way up to iron are formed in the cores of stars as they undergo nuclear fusion. as stars age they produce heavier and heavier elements.this process is called \stellar nucleosynthesis\. remember, the word \stellar\ refers to stars, so these elements are formed in the core of stars as they go through the process of nuclear fusion.
• elements created in supernova explosions: all elements heavier than iron (26) all the way up to plutonium (94) are produced in the extreme conditions of supernova explosions as massive stars die. this process is called \supernova nucleosynthesis\

elements bigger than ______ were formed by supernova explosions?
○ c, carbon
○ h, hydrogen
○ he, helium
○ si, silicon
○ o, oxygen
○ fe, iron

Explanation:

The text states that all elements heavier than iron (26) are produced in supernova explosions. Among the options, iron (Fe) is the element such that elements bigger than it are formed by supernova explosions.

Answer:

Fe, Iron
