Question

Which of the following actions occur during the process of fusion?

1.)atoms are divided
2.)atoms are broken apart
3.) atomic nuclei are united
4.)atomic nuclei are split

Answer 1

atomic nuclei are united

Answer 2

Answer: 3.) atomic nuclei are united

Step-by-step explanation:

Nuclear fusion is a process which involves the conversion of two small nuclei to form a heavy nuclei along with release of energy.

`4_1^1\textrm{H}\rightarrow _2^4\textrm{He}+2_(+1)^0\textrm{e}+\text{energy}`

Nuclear fission is a process which involves the conversion of a heavier nuclei into two or more small and stable nuclei along with the release of energy.

`_(92)^(235)\textrm{U}+_0^1\textrm{n}\rightarrow _(56)^(143)Ba+_(36)^(90)Kr+3_0^1\textrm{n}`

Thus if a heavier nuclei is being formed from two smaller nuclei, this is a nuclear fusion reaction.
