Question

Paraphrase the following selection.

Nuclear energy becomes available when radioactive (unstable) atoms split apart. The natural or artificial breaking up of atoms into smaller pieces is called fission. The newly discovered ability to "split" the atom is what makes atoms into a source of energy--nuclear energy.

Scientists discovered that uranium 235 can be caused to split apart when hit by a neutron traveling at a medium speed. The uranium atom divides and subsequently becomes two new elements, barium and krypton.

Answer 1

Nuclear energy becomes present when radioactive atoms split the split of atoms is called fission this can make atoms a source of energy. Scientists discovered that uranium 235 can be split when hit by a neutron going at medium speed when the uranium atom splits it becomes barium and krypton.

Step-by-step explanation:

Answer 2

"Nuclear energy is available when unstable atoms split. the natural or artificial splitting of atoms is called fission. The ability to split is what makes atoms a source of nuclear energy, Scientists have found out that uranium 235 can be split apart by being hit by neutrons going at medium speed. Uranium atoms divide and eventually become two new elements, barium and krypton."
