Question

nuclear fusion: inside a stars core, extreme heat and pressure cause smaller atomic nuclei to fuse together, forming heavier elements in a process called nuclear fusion. this process releases a tremendous amount of energy, which is emitted as radiation and reaches earth.
label the diagram below with the following words: lighter element and heavier element

Explanation:

In nuclear fusion, smaller (lighter) atomic nuclei fuse to form larger (heavier) ones. Hydrogen (\(H\)) is a light - weight element. The product of the fusion (the larger nucleus) is a heavier element.

Answer:

The two hydrogen (\(H\)) labels should be labeled as "lighter element". The product (the larger nucleus) should be labeled as "heavier element".
