Answer 1

Explanation:

1)A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a self-sustained nuclear chain reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion.

2)Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes

3)You know that neutrons are found in the nucleus of an atom. ... Neutron numbers are able to change the mass of atoms, because they weigh about as much as a proton and electron together. If there are many atoms of an element that are isotopes, the average atomic mass for that element will change
