Nucleosynthesis

What is nucleosynthesis?

• How the sun creates new hydrogen atoms out of dark matter

• The formation of a cell's nucleus

• The formation of new elements only in stars

• The formation of new elements by the Big Bang, in stars, in supernova and particle accelerators

Smaller mass elements like Carbon and Oxygen are formed in stars

• True

• False

Do all stars make energy through fusion?

• Yes
• No
• Just our sun
• Only large stars

Define nuclear fusion.

• Nuclear fusion – combining lighter atoms to make heavier ones – is what makes it possible.

• Nuclear fusion – splitting lighter atoms to make heavier ones – is what makes it possible.
