Which element is nuclear fusion least likely to produce? hydrogen, which has an approximate mass of 1 chlorine, which has an approximate mass of 35 argon, which has an approximate mass of 39 silicon, which has an approximate mass of 28

## Step 1<br />Nuclear fusion is a process where two light atomic nuclei combine to form a heavier nucleus. This process is most likely to produce elements with lower atomic masses, such as hydrogen, which has an approximate mass of 1.<br /><br />## Step 2<br />The fusion process is less likely to produce elements with higher atomic masses, such as chlorine, which has an approximate mass of 35, argon, which has an approximate mass of 39, and silicon, which has an approximate mass of 28.<br /><br />## Step 3<br />The fusion process is most likely to produce elements with lower atomic masses, such as hydrogen, which has an approximate mass of 1.
