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

When radioactive atoms split apart, nuclear energy becomes available. Fission is when the natural or artificial atoms break into smaller pieces. Nuclear energy is what when atoms split and become a source of energy. Uranium 235 splits when a neutron travels at a medium speed. Uranium atoms divide to become barium and krypton.

Step-by-step explanation:

Answer 2

When radioactive atoms split apart, nuclear energy becomes available. Fission is when the natural or artificial atoms break into smaller pieces. Nuclear energy is what when atoms split and become a source of energy. Uranium 235 splits when a neutron travels at a medium speed. Uranium atoms divide to become barium and krypton.
